Meagan Wolfe, Wisconsin Elections Commission administrator, joined ABC News Live to discuss Election Day preparations and urged voters, at this point, to drop off their ballot in person or in a dropbox rather than rely on the Postal Service.

"We're at this critical juncture before the election, returning your absentee ballot either in person to your local election official or in a Dropbox in your community is really the best option," Wolfe told ABC News Live Prime Anchor Linsey Davis.

Since so many Wisconsin residents have voted early or will over the next few days, Wolfe said she does not anticipate Election Day crowds being an issue.

"We expect that there'll be about 40% of our expected turnout that come to the polls on Election Day," she said.

While Trump was speaking at his second rally in Arizona and stumping to Latino voters, he mentioned the "American Dream Plan," a new plan targeted towards Latino and Hispanic communities nationwide.

According to the campaign, the plan is promises to add 500,000 Hispanic-owned businesses, increase capital for minority entrepreneurs through Opportunity Zones, create 2 million new jobs for Hispanic Americans, increase access to home ownership, bolster school choice programs, and deliver a resolution to the Deferred Action for Childhood Arrivals (DACA) program with a permanent solution that benefits both Americans and recent arrivals.

'Latinos for Trump' advisory board member Alfredo Ortiz said that Trump's "American Dream Plan" gives Hispanic Americans another reason to vote for Trump.

Earlier Wednesday the Trump campaign also launched three new Spanish-speaking ads targeted towards Latino voters in South Florida, Central Florida, Arizona and Nevada.

After relentlessly downplaying the virus at recent rallies this week, disparaging testing, and complaining about the media's continued coverage of the worst pandemic in a century that continues to surge -- Trump at his Goodyear, Arizona, rally appeared to pull back those comments a bit.

The president did not mention the word "COVID," as he has been, often repeating it multiple times seemingly exasperated by having to discuss the virus.

Trump also didn't explicitly say "we are rounding the turn" or try to uses testing as an excuse for the surging cases. But the president did continue to claim he's done "a great job we've done in fighting the China virus," and claimed he was "immune" while sharing a fist-bump on stage with Sen. Rand Paul. The immunity duration after contracting COVID-19 remains unknown, according to experts.

ABC News Live got an exclusive look at how election officials in Washington, D.C., perform signature verifications before mail-in ballots are counted.

Trained staff manually inspect each handwritten script and visually compare it to an electronic version associated with the voter's driver's license or other official record.

At an event with truckers in Las Vegas, Trump was asked about the unrest in Philadelphia following the death of Walter Wallace Jr., a Black man, at the hands of police. After condemning riots in what he called the "Democrat run" state, he said the federal government is looking into the fatal shooting.

"It's a terrible thing," Trump said. "What I'm witnessing is terrible, and, frankly, that the mayor or whoever it is, that's allowing people to riot and loot and not stop them is also just a horrible thing."

"We're looking at the shooting and if asked to go in and help, we will do that," Trump said, urging Philadelphia Mayor Jim Kenney, a Democrat, to call in the National Guard -- which the state has already done.

Looking to the election, Trump also said that "hopefully" the courts will stop ballots from being counted past Nov. 3 -- but experts say to expect record amount of mail-in voting, election night could be more like election week.

Biden, asked earlier about the ongoing situation in Philadelphia, gave a general answer to the ongoing clashes between police officers and protesters as he tries to walk a fine line of supporting both Black Lives Matter protesters and law enforcement.

“There is no excuse whatsoever for the looting and the violence. None whatsoever. I think to be able to protest is totally legitimate, totally reasonable," Biden said, going on to pitch his idea of a national commission on policing. "But there's no excuse for the looting."
