Official youth turnout won't be known for several days, but analysis of early voting showed large increases in turnout of 18 to 29-year-olds at this year's polls.

From Taylor Swift to the #VoteForOurLives campaign - the BBC's Georgina Rannard takes a look at the power of America's young voters.

Stormy Daniels' lawyer Michael Avenatti, who has said he wants to run for president in 2020, has told the BBC's Today programme that "people want fighters" to take on Donald Trump in the next election.

After several losses further east, the Democrats have finally picked up a Republican seat in the Senate.

But the gain comes too late to prevent a Republican majority in the chamber.

• Republicans have consolidated their lead in the Senate - and are currently confirmed to have 51 seats
• The Democrats have reached the 218 seats they need to take control of the House - a significant blow to President Trump
• They also made gains in governor races - gaining six states from Republicans so far

Democrat Tony Evers has beaten incumbent Republican Governor Scott Walker in a nail-biting race in Wisconsin.

The race was on a knife-edge all night, with former teacher Mr Evers leading by only about 30,000 votes with 99.62% counted.

Observers say his win will buoy the Democrats' hopes for Wisconsin in 2020, after the state swung red for Donald Trump in 2016.

The Democrats are now confirmed to have won 218 seats in the House of Representatives, assuring them of a majority.

The first national newspapers are publishing their verdicts on the mid-term results.

The Washington Post leads on the Democrats' House victory, while the New York Times and Wall Street Journal reflect the split of Congress results.

Brothel owner and reality television star Dennis Hof, who passed away last month, has posthumously been elected in Nevada.

During his campaign for the state assembly, the flamboyant 72-year-old labelled himself the "Trump from Pahrump".

Because he isn't alive to serve, his seat will be considered vacant and another Republican will be selected by local county commissioners to serve his two-year term.

Hof's campaign manager Chuck Muth described election day as "bittersweet".

“It’s kind of like Moses,” Muth told ThinkProgress on Tuesday, external. “He’s not going to make it to the promised land with us… but we hope he’s watching from the great beyond.”

The Democratic candidate for governor in Georgia has said she will not concede victory until "every single vote" is counted.

As it stands, Stacey Abrams's Republican opponent Brian Kemp leads by about 100,000 votes with 99.95% precincts reporting.

"I am here today to tell you there are votes remaining to be counted. Voices are waiting to be heard," she told her supporters in the early hours of Wednesday.

"Across our state folks are opening up the dreams of voters and absentee ballots and we believe our chance for a stronger Georgia is just within reach.

"But, we cannot seize it until all voices are heard and I promise you tonight we're going to make sure that EVERY vote is counted."

If she had won, Ms Abrams would have become the first black female governor in the history of the US.

Voters in San Francisco have voted in favour of Proposition C – a controversial measure supporters say will greatly help the city solve its crippling homelessness crisis.

It will bring in an estimated $250m-$300m a year in added taxes from around 400 of the city’s biggest companies, to be spent specifically on the problem.

Naturally, this means the measure has been seen as a tax on the tech giants that dominate this part of the world – firms that are often blamed for driving up living costs, pushing thousands onto the streets.

More than $7m was spent on campaigning; most of the money ($5.7m) went towards backing the measure.

Prop C’s biggest supporter was Marc Benioff, the charismatic chief executive of Salesforce – a firm which would be among those taxed. Mr Benioff, who most suspect has political ambitions of his own, backed the campaign with around $1m of his own money.

Those against the bill included Twitter’s Jack Dorsey, who engaged in very public debates with Mr Benioff about the merits of the plan on, where else, Twitter.

Perhaps surprisingly, one critic of the tax was the city’s mayor, London Breed. She cited a lack of adequate accountability for existing funds to fight homelessness as a reason not to gather even more.

But, it passed. The money will go to things like rent subsidies, permanent housing help, hygiene measures and more. It won’t solve homelessness overnight, but as far as a majority of San Francisco voters are concerned – it’s a start.

Republican Congressman Steve King has narrowly held his House seat in Iowa.

Mr King has a long history of making racially incendiary comments, and days before the election received a sharp rebuke from his own party chairman, Steve Stivers.

Mr King received fresh condemnation over reports he had met members of a far-right Austrian party founded by a former Nazi officer on a trip funded by a Holocaust memorial group.

Three big corporations dropped him - but he still won a ninth congressional term on Tuesday, edging past Democrat J D Scholten.

Alexandria Ocasio-Cortez and Abby Finkenauer - both 29 - are set to become the youngest women to ever serve in the US Congress.

Ms Ocasio-Cortez, dubbed a rising star in the Democratic party in the run-up, stormed to victory with more than 78% of the vote in New York's 13th district.

Ms Finkenauer has more than 50% of the vote in Iowa's first district and will unseat Republican Rod Blum.

Like other millennials, she has been open about not being able to afford her own home and her struggle to pay off her student debt.

A county clerk in Kentucky who was jailed for failing to issue same-sex marriage licences has lost her bid for a second term in the role.

Republican Kim Davis, who became a conservative heroine after refusing to abide by the landmark 2015 Supreme Court ruling legalising same-sex marriage, was defeated by Democrat Elwood Caudill Jr.

It's not just governors and members of Congress that people have been choosing.

Voters in Michigan have approved a proposal to make recreational cannabis use legal.

The measure will allow adults over 21 to possess, grow and use small amounts legally and should be rolled out later this month.

It makes them the 10th state nationally, and first in the mid-west, to do so.

Marijuana is legal in 30 states, including Michigan, for medical reasons.

The battle for the Florida Senate seat remains too close to call. Republican Rick Scott, the state's outgoing governor, maintains a narrow lead at 50.3% of the vote while incumbent Democrat Bill Nelson has 49.7%.

Only around 55,000 votes separate the two.

Mr Scott, however, has already claimed victory and President Trump has reportedly called him to offer congratulations.

A spokesman for Mr Nelson said the senator would give a speech on Wednesday regarding the election.

"Our greatest days are still ahead," says Beto O'Rourke, who lost his campaign against incumbent Republican Ted Cruz in the past hour.

He called upon politicians to write laws that "come not out of fear, but out of confidence".

Americans must "live up the promise and potential of this country", he said on a stage in his hometown of El Paso, Texas.

He said his supporters are made up of "people from all walks of life coming together, damning the difference and deciding that what unites us is far stronger than the colour of our skin, how many generations of us we can count ourselves... who we pray to, whether we pray at all..."
