Democrats will be disappointed by that performance from their VP contender Tim Walz. He seemed nervous, he repeatedly stumbled over his words and his arguments were unsteady. He was less charming daggy dad and more bumbling uncle.
For a man vying to be "one heartbeat away" from the presidency, it was an unimpressive outing.
He seemed rusty and perhaps the Democratic strategy which has seen both Walz and Kamala Harris mostly avoid hard interviews might have left him unprepared to debate JD Vance.
He did improve as the debate went on. Among his strongest moments came towards the end when he prosecuted the case on the January 6 attack on the US Capitol; painting Donald Trump as a threat to democracy and JD Vance as someone who wouldn't even admit Trump lost the last election.
Vance by comparison seemed sharp and calm. He was also surprisingly amiable towards Walz, which might have shocked people who expected him to be a snarky and unlikeable guy.
He was disciplined, deftly pulling the debate constantly back to some of the stronger points for Republicans, like immigration, and tying Kamala Harris to Joe Biden's unpopular presidency.
Vice-presidential debates are not usually major factors in US elections and it's unlikely anything said tonight will make a huge difference in this race.
Walz will be embarrassed by his performance but he hasn't fatally wounded his ticket. There will be greater pressure for both Walz and Harris to answer more tough questions, though, to see if they deserve the White House.
