The Trump campaign has already branded him a "dangerously liberal extremist" and a “far-left lunatic”.
They point to Tim Walz’s record in Minnesota of enacting progressive social programmes and accuse him of not doing enough to control the demonstrations that broke out after the death of George Floyd at the hands of Minneapolis police officers in 2020.
At the very least, Republicans may welcome not having to face off against Josh Shapiro, who has a more centrist profile and might have given Kamala Harris a decisive boost in Pennsylvania.
JD Vance, Walz's Republican adversary for the vice-presidency, said Harris's choice of running mate shows she is willing to "bend the knee to the most radical elements of her party".
Trump, meanwhile, said Walz will unleash "HELL ON EARTH and open our borders to the worst criminals imaginable".
But even if Walz provides a more inviting target for Republicans, making that rhetoric stick on his friendly, meat-and-potatoes persona will be no easy task for the Trump campaign.

Democratic vice-presidential candidate Tim Walz’s military record has been closely scrutinised since he was announced as Kamala Harris's running mate.
Historic accusations made by some veterans have been revived by his opposite number, Republican JD Vance, who himself served in the military.
Walz served for 24 years in the Army National Guard - but Vance has claimed that “when Tim Walz was asked by his country to go to Iraq, you know what he did? He dropped out of the army and allowed his unit to go without him".
We’ve looked at the sequence of events at the time of Walz’s departure from the military:
In February 2005 he filed an application to run for Congress. The following month it was announced that there would be “a possible partial mobilisation” of troops from the Minnesota National Guard to Iraq within the next two years.
In May that year, Walz retired from the National Guard to focus, he said, on his election campaign, which he ultimately won.
In July 2005, his National Guard unit received orders to mobilise for Iraq and was deployed there in March 2006
Vance also said Walz has been dishonest about his role in the military.

Donald Trump loves to compare crowd sizes. And the Harris campaign knows it. They have even been mocking him over it on his own social media platform, external.
Tuesday's event in Philadelphia was packed. I spotted a few empty spots, but for the most part the 10,000-seat arena was full. It was after all the first event where Harris unveiled her running mate Tim Walz.
Last night, Harris continued giving Trump a run for his money - doing something out of his playbook by pulling up in Detroit at an airport hangar with Air Force 2 plane in view to be greeted by a huge crowd. Her campaign says more than 12,000 people are out tonight.
But does size matter?
Huge crowds and lines of cars aren’t always a barometer of a campaign’s destiny. In 1984, Democratic nominee Walter Mondale was trailing Ronald Reagan but pointed to the size of his crowds as a sign of enthusiasm that would translate into votes at the ballot box.
The same thing happened with Democratic nominee Michael Dukakis four years later when he was trailing Republican nominee George H W Bush.“I smell victory in the air don’t you?" he told a large crowd in Kentucky on his final weekend on the campaign trail.
He also lost.
Rallies are simply to "rally" supporters into a deeper commitment - but that doesn’t mean there’s no political benefit at all.
They can often be an incentive for people to find out more to check out the hype around a candidate or to actually ensure those who back a candidate will donate money and actually vote.

Donald Trump has been very vocal on his Truth Social platform this morning, posting dozens of updates ahead of his news conference at 14:00 EDT (19:00 BST). The former president says when he eventually debates Kamala Harris, he will “expose” her “the same way I exposed Crooked Joe”.
Trump also claims Harris, who officially became the Democratic nominee in recent days, “refuses to do interviews because her team realizes she is unable to answer questions”.
He took aim the media for how it reports the size of the crowds at their respective rallies, saying: “If Kamala has 1,000 people at a Rally, the press goes ‘crazy,’ and talks about how ‘big’ it was… when I have a rally, and 100,000 people show up, the fake news doesn’t talk about it”.

Image source, EPAKamala Harris and Tim Walz were scheduled to travel to campaign events in North Carolina today, but their plans were foiled by Tropical Storm Debby, which is drenching the southeastern US coast.
The storm has also forced the cancellation of Harris-Walz events in South Carolina and Georgia this week.
Republican VP candidate JD Vance, who has been following the Democrats' campaign map to hit the trail in the same states as them, has also cancelled an event in North Carolina as intense rain and flooding have battered the region.
At least five people were killed after Debby slammed into Florida as a category one hurricane before weakening to a tropical storm.
The storm unleashed prolonged downpours and flooding to historic southern US cities.
In the coming days, Harris and Walz are headed to events in Arizona and Nevada.

Trump’s news conference comes after a new national survey was published which shows Vice-President Kamala Harris leading as the choice for president.
The survey, published by Marquette Law School, external, shows 52% of registered voters want Harris for president, while 48% chose former president Trump.
Among likely voters - those who have indicated they strongly intend to vote - Harris leads Trump by six points, 53% to 47%.
This suggests Harris is outperforming Biden's previous support, before the president dropped out of the race - a Marquette poll back in May put Trump and Biden neck and neck among registered voters, while Trump took 51% of likely voters and Biden 49%.
In reaction to Harris becoming the Democratic nominee, 87% were very or somewhat satisfied.
While political news is unfolding throughout the US today, Wednesday's campaign events were laser-focused on the Midwest, especially the region’s swing states. Here’s a brief recap of what went down yesterday:
