John Kasich says his win in Ohio dealt Donald Trump a "very, very big blow" to getting the number of delegates required to win the Republican presidential nomination.

Neither Mr Trump nor Ted Cruz could "come into Ohio with the philosophies they have and win. And if you can't win Ohio, you can't be president", he told NBC's Today programme.

Mr Kasich said that "nobody is going to have enough delegates" by the time of the Republican National Convention in Cleveland in July to win the nomination outright - triggering a brokered convention.

Democratic front-runner Hillary Clinton's latest victory speech has come under fire from some commentators who criticised her for "shouting" and coming across as "mad". 

But critics were quick to point out much of the criticism - which included her being accused of "shouting angrily" and told to adopt a more "conversational tone" and "smile" - came from men.

Gordon Kerswell-Reid, 26, from Leicester in the UK, met Hillary Clinton in January and quizzed her about his local football team's chances of winning the English Premier League, local newspaper the Leicester Mercury has reported, external.

"Hilary stopped to speak to me for a minute and I even managed to ask her if she thought Leicester City Football Club, external would win the Premiership. I'm not sure if she knew who the team was, but she replied yes," Mr Kerswell-Reed said.

The business student volunteered for the campaigns of Mrs Clinton and Republican Donald Trump in order to meet them both.

"What amazed me was how accessible they were. One woman I spoke to over there had Hillary Clinton in her home and that was seen as perfectly normal. That just doesn't really happen over here and it needs to," he added.

Republican presidential front-runner Donald Trump has warned of possible violence if he goes into a brokered convention with a majority and his party attempts to nominate another candidate.

"You'd have riots," he told CNN's New Day programme.

He told anchor Chris Cuomo: "I wouldn't lead it," but unrest could happen. 

"The really big story is how many people are voting in these primaries," he said. "If you just disenfranchise these people, I think you would have problems like you've never seen before," he said.

Mr Trump posited a hypothetical scenario where he went into a convention with about 1,100 delegates and his nearest rival went in with about 500.

He said he couldn't imagine failing to get the party's nomination virtually "automatically" and said "I don't even want to think about" what he would do if he did not get the nomination.

"Trump has smashed the Republican Party,"Die Welt'sUS correspondent says, external, arguing that the chances of blocking Trump's nomination through a brokered convention seem remote.

In contrast, a report in, externalDer Spiegel says there's a growing likelihood of a "chaos scenario" emerging in the Republican primaries, whereby Trump will fail to win an overall majority of delegates, opening the door for an attempt to unite behind an anti-Trump candidate in a contested convention. 

"Will the party fall apart because of Trump?" theFrankfurter Allgemeine Zeitung wonders in an online commentary, external. 

Pointing out that the party establishment finds both front runners - Mr Trump and Ted Cruz - unpalatable, it concludes: "The Republicans are now reaping the whirlwind they at least partly sowed themselves with their policy of obstruction in Washington."

TheSueddeutsche Zeitung expresses amazement, external at the "boundless loyalty of the Trump fans", adding: "His opponents' campaigns to portray him as a sexist charlatan and a racist are too late by several months."

It also declares, external Senator Marco Rubio's "humiliating" departure from the race a "disaster" for the Republicans.

Le Mondesees, external Sen Marco Rubio as having been "crushed" in his own stronghold of Florida but thinks, external an outright majority of delegates and the nomination may still not be in the bag for for Mr Trump, especially with "many party officials considering all possible means to block his path".

Le Figarobelieves, external the property tycoon's delivered the "promised knock-out" against Mr Rubio with a win in the senator's home state of Florida.

And this, it adds, "despite millions of dollars of negative ads from big Republican party donors and criticism from all parts of the political spectrum and an overwhelming majority of the US media". 

French dailyLiberationcompares, external Mr Trump to a "powerful avalanche sweeping away everything in its path".

Looking at the Democratic contest, the "game appears to be over", according to, externalLa Croix.

Hillary Clinton "now has the upper hand in the campaign", the daily says, arguing that the former first lady has shown that she can beat Bernie Sanders among the blue-collar workers of Ohio and Illinois, as well as the south.

BBC Washington Correspondent Gary O'Donoghue, external says Republican candidate John Kasich is now the "darling of the Republican establishment" after he beat front runner Donald Trump in Ohio.

Mr Kasich will now be "hoping for a contested convention", our correspondent told BBC World News, because that's the "only way he'll get to the White House". 

Ted Cruz, currently behind Donald Trump in the race for the Republican nomination, has said that a brokered convention would be an "absolute disaster".

He told CNN's New Day that some Republicans were having "fevered dreams" about a convention that would enable them to "parachute in an establishment candidate" and "save the fears of the lobbyists".

But "people would quite rightly revolt", Mr Cruz said, adding that the way to defeat Mr Trump was at the ballot box.

Political website The Hill estimates, external that Donald Trump will fall about 100 delegates short of the 1,237 needed to secure the Republican nomination outright.

That would send the Republicans into a contested or brokered convention.

As the BBC's Rajini Vaidyanathan and Anthony Zurcher explain, this is a free-for-all in which delegates gained by candidates during the primary process are all up for grabs again.

The nominated presidential candidate to emerge from the haggling, which can take days or weeks, does not even have to be one of the candidates who have been through the marathon of primaries.

As CNBC reported, external earlier, House Speaker Paul Ryan has not ruled out accepting the Republican nomination for president if the party holds a brokered or contested convention.

Chris Cillizza from the Washington Post explains why Marco Rubio's bid for the nomination was doomed to fail.

He says two big moments went against him. The first was when he was caught repeating himself in a TV debate and the second was when Mr Cillizza says he "got down in the gutter with Donald Trump", saying he looked "sweaty", appeared to have "wet his pants" and had "small hands, external".

But Mr Cillizza says the 44-year-old has talent and "will probably run again" for his party's nomination in the future.

The NYT editorial board, external also has a few barbs for Democratic front runner Hillary Clinton: "The weakness of her appeal among the young, independents, men and some working-class voters cannot be ignored," it says.

Her rival Bernie Sanders has had success as "the voice of Democrats resentful of a party establishment that has been too tepid in taking on issues like income inequality", it adds.

The newspaper believes Mrs Clinton can win over the sceptics if she stops "dodging some aspects of her record. That includes speaking with greater detail and complete candor about her changes on policy positions" including gay marriage, immigration and trade agreements.

The New York Times says, external the Republican party "appears headed for disaster" after what it says have been "decades of pandering to intolerance while working against the needs of working-class Americans and minorities".

The paper says the party must now decide whether to embrace Donald Trump "as its nearly inevitable nominee and be defined — or even destroyed, as some conservatives suggest — by his odious candidacy, or reject him in hopes that one of his remaining competitors will snag the nomination in a brokered convention".

That's what a lot of people are asking on Twitter. The media hasn't projected a winner in either contest in the state because it's too close to call. That's because the margins between Donald Trump and Ted Cruz in the Republican race, and Hillary Clinton and Bernie Sanders in the Democratic race, are less than half a percentage point. 100% of precincts have reported, but some absentee and provisional ballots remain uncounted.

CNN says, external the recount law in Missouri allows a second-place finisher to request a recount if the margin of victory is less than half a percentage point.

The candidate who became the establishment's last hope was thoroughly defeated in his home state of Florida and bowed out of the race on Tuesday night. In a final bit of ignominy he was heckled even as he gave his concession speech.

Maybe there's an alternate universe where the senator didn't have a miserable debate in New Hampshire and subsequent collapse in that state's primary.

Perhaps he would have cleared the field quickly after that and engaged in a long, gruelling battle against Mr Trump and Mr Cruz for the nomination.

Maybe he would have lost the nomination anyway - but it would have been closer.

Mr Rubio can dwell on those thoughts in the coming weeks and months, while a very different Republican reality takes shape without him.

It looks like the Sanders post-Michigan boomlet will be short-lived. Ohio and Illinois didn't go his way, and Florida and North Carolina delivered devastating blows. He may narrowly prevail in Missouri, but he continues to lose ground to Mrs Clinton in the delegate count.

He started this campaign as a message candidate, but after a narrow loss in Iowa and a massive win in New Hampshire it seemed he may legitimately challenge Mrs Clinton for the nomination. His inability to make inroads among minority voters in the south - and now, it seems, in much of the mid-west - will likely prove his undoing, however. He found a compelling message for some disaffected liberals, but that's all he'll be left with soon.

There are a number of states in the coming weeks that could provide wins for Mr Sanders. But he doesn't need wins at this point - he needs massive victories. And, barring a major reversal of fortune, that just isn't going to happen.

"Tonight was a good night," Ted Cruz said at his rally Tuesday in Houston, Texas. "Tonight we continue to gain delegates and continue our march to 1,237."

While the senator did gain some delegates, it's hard to contend that this was a good night for him. He's in a close battle with Mr Trump in Missouri, but if he loses there he'll only pick up a handful of delegates.

It seems possible that he'll get completely shut out in Illinois. In North Carolina - part of the southern block of states that was supposed to be his stronghold - he finished second to Mr Trump.

Mr Cruz has repeatedly asserted that he's the only candidate besides Mr Trump who has a "plausible" path to the nomination through the primary process. But those odds are getting longer by the day.

As one of the last three candidates standing there's no question that Mr Cruz has run a skilful campaign.

His decision to cosy up to Mr Trump in the early phases of the race probably paid dividends, as the New Yorker turned his ire toward other candidates.

Mr Cruz may find out, however, that if you make nice with the tiger all it means is you get eaten last.

First the good news. The Ohio governor won his home state and the 66 delegates that go along with it. He more than doubled his total at this point, to 136 delegates. He was able to give a victory speech and enjoy a massive confetti shower.

The bad news is that it's effectively impossible for Mr Kasich to win the nomination in any scenario that doesn't involve a brokered convention.

And that Ohio win? In modern US political history no incumbent governor has ever lost his home state. In fact, very few former governors have lost their states either (if they stayed in the race long enough to compete).

Mr Kasich's Ohio win, while notable for the obstacle it places in Mr Trump's path to the nomination, could be nothing more than a blip. He'll have to ramp up his campaign quickly to compete with Mr Cruz and Mr Trump over the coming weeks.

While Ohio may give anti-Trump Republicans some measure of hope, sooner or later they are going to have to make a choice. Do they try to wrest the nomination away from the New Yorker in a bruising floor fight at the convention in July or do they give up the ship and start organising for a third-party conservative campaign?

Mr Kasich is betting that he could benefit from the former - but, at this point, there are forces within the conservative movement who may opt for disunion, external.

After Tuesday night's results, Mrs Clinton will breathe much easier.

The South once again proved to be Mrs Clinton's bulwark, as she racked up big wins in Florida and North Carolina - and reaped the sizable delegate bounties. And whatever magic her rival Bernie Sanders had in Michigan did not reappear in Ohio and Illinois.

Mrs Clinton is continuing to pull away from Mr Sanders and, at this point, seems firmly in control of the race. She only has to win 42% of the remaining delegates to secure the nomination.

In her victory speech on Tuesday night she turned her attention to Donald Trump - incorporating some of the populist economic rhetoric that Mr Sanders has shown to be an effective way to rally the Democratic base.

Her election results weren't all good news, however. Exit polls reveal that even Democrats continue to have doubts about her character.

In Ohio, for instance, among voters who rated honesty as the most important attribute in a candidate, Mr Sanders beat her 73% to 26%.

Confident, front-running Hillary Clinton is back, though. In the past, that's been when she's most susceptible to electoral stumbles - but she has a lead that will be very difficult to lose.
