MILWAUKEE (AP) — Vice President Kamala Harris and former President Donald Trump will host dueling rallies within seven miles of one another on Friday night in the Milwaukee area as part of a final push for votes in swing-state Wisconsin's largest county.

Milwaukee is home to the most Democratic votes in Wisconsin, but its conservative suburbs are where most Republicans live and are a critical area for Trump as he tries to reclaim the state he narrowly won in 2016 and lost in 2020. One reason for his defeat was a drop in support in those Milwaukee suburbs and an increase in Democratic votes in the city.

"Both candidates recognize that the road to the White House runs directly through Milwaukee County," said Hilario Deleon, chair of the county's Republican Party.

The dueling rallies — Trump is in downtown Milwaukee and Harris is in a suburb — may be the candidates' last appearances in battleground Wisconsin before Election Day. Both sides say the race is once again razor tight for the state's 10 electoral votes. Four of the past six presidential elections in Wisconsin have been decided by less than a point, or fewer than 23,000 votes.

It was absentee votes from Milwaukee, which typically are reported early in the morning after Election Day, that tipped Wisconsin for President Joe Biden in 2020.

Democrats know they must turn out voters in Milwaukee, also home to the state's largest Black population, to counter Trump's support in the suburbs and rural areas. Harris is hoping to replicate, and exceed, turnout from 2020 in the city, which voted 79% for Biden that year.

Trump is trying to cut into the Democrats' margin. Deleon called it a "lose by less" mentality.

A lot of Democrats are "anxious and cautiously optimistic," said Angela Lang, founder and executive director of Black Leaders Organizing for Communities in Milwaukee.

"Especially given 2016 when there wasn't the same amount of energy, I think it's clear Dems learned lessons about the importance of Milwaukee and Wisconsin as a whole," she said.

In another late outreach effort targeting Black voters, former President Bill Clinton campaigned with local faith leaders on Thursday night at a center for celebrating African American music and arts in Milwaukee.

Hillary Clinton did not campaign in Wisconsin in 2016 after her primary loss, a mistake that Harris is not repeating. The Friday stop will be her ninth in the state as a presidential candidate and her fifth to Milwaukee or its suburbs. It will be Trump's 10th stop in Wisconsin, not counting the Republican National Convention, which was held in Milwaukee, and his third visit to the Milwaukee area.

Wisconsin Republican Party Chair Brian Schimming said that Harris having to return to the Democratic stronghold of Milwaukee shows she is on defense while Trump is on offense.

The Milwaukee Election Commission estimated on Thursday that it expects to receive more than 100,000 ballots by Election Day. But that lags early vote returns from the conservative suburbs.

"The question no one knows the answer to is who those voters are voting for," said Wisconsin Democratic Party Chair Ben Wikler. "My feeling is that there may be some pleasant surprises for Harris."

Lang, the Milwaukee organizer, said it is a tradition for many voters her group contacts to cast their ballots on Election Day. And if they don't?

"Then we're in a world of trouble," said Mandela Barnes, a former lieutenant governor and president of Power to the Polls, a group that's been working to boost turnout.

Trump's rally is being staged in the same arena where the Republican convention took place three months ago. The Harris rally, to be held at the state fair park in West Allis, will include the rapper Cardi B, who is slated only to speak, and performances by GloRilla, Flo Milli, MC Lyte, The Isley Brothers and DJ GEMINI GILLY.
