JUNEAU, Wis. (AP) — Donald Trump on Sunday visited Wisconsin for the fourth time in eight days as his campaign showers attention on a pivotal state where Republicans fret about his ability to match Democrats’ enthusiasm and turnout machine. “They say that Wisconsin is probably the toughest of the swing states to win," Trump said in his opening remarks at an airplane hangar in a rural Juneau where the overflow crowd spilled out on to the tarmac.

"I don’t think so.” Voters in Wisconsin are already casting absentee ballots and in-person early voting begins Oct. 22.

Trump encouraged supporters to vote by mail and early, when the time comes, so they turn out “in record numbers.” Wisconsin is perennially tight in presidential elections but has gone for the Republicans just once in the past 40 years, when Trump won the state in 2016. A win in November could make it impossible for Democratic nominee Kamala Harris to take the White House.

“In the political chatter class, they’re worried,” said Brandon Scholz, a retired Republican strategist and longtime political observer in Wisconsin who voted for Trump in 2020 but said he is not voting for Trump or Harris this year. “I think Republicans are right to be concerned.” Trump won the state in 2016 over Democrat Hillary Clinton by fewer than 23,000 votes and lost to Democrat Joe Biden in 2020 by just under 21,000 votes.

On Tuesday, Trump made his first-ever visit to Dane County, home to the liberal capital city of M.
