The Biden campaign in Michigan has a tremendous ground-game advantage

Ms Dingell was speaking at the opening of one of 30 campaign offices that Mr Biden’s campaign will soon have operating across the Wolverine State, a decisive swing state during the past two presidential elections. In 2016 Mr Trump won Michigan with a margin of just 0.3%. In 2020 Mr Biden took it back for the Democrats by 2.8%. State Democratic officials are confident that they can repeat the trick this year, and they cite a remarkable campaigning machine built since 2017 as evidence. “We are organising and talking to voters all the time,” says Lavora Barnes, the Democratic chairwoman. But Ms Dingell’s warning rings true too. Michigan is thus a good place to take the pulse of Mr Biden’s campaign. The president is running a traditional playbook, while Mr Trump’s approach to electioneering is as unconventional as ever.
