Election 2020 updates: Trump ends long day rushing through final rally

Harris’ first stop in Texas was Fort Worth, where she gave remarks to a socially distanced and masked crowd of about 300 supporters outside of First St. John’s Cathedral -- her presence in the state significant as she’s the first Democrat vice presidential candidate to campaign there since 1988.

After the state shattered its 2016 voting record this morning, Harris praised the more than nine million votes already cast in Texas -- but reminded the race isn’t over yet. 

“Today is the last day of early voting in Texas and you all have been doing your thing! What did I hear? Was it 9 million people have voted so far?" Harris said. "Now, we know this is no time to let up on the pedal though, right?"

Urging Texans to vote whether early or on Election Day, she repeated her mantra that voting is one of the best ways to “honor the ancestors,” paying special tribute to the late Congressman John Lewis. 

“John Lewis lived a life that was about a commitment to fighting for equal rights and civil rights, and it was fight that was born out of being a patriot and loving our country,” she said. “Knowing the best way we achieve our ideals, is to fight for those ideals, to do it in every way by standing up, showing up and speaking up -- so we must vote to honor the ancestors.”

Though winning the state’s 29 electoral college votes is a longshot for the party, some Democrats sense an opportunity to snatch the GOP-stronghold for the first time in more than four decades, while others warn the campaign should stay focused on states Clinton narrowly lost in 2016.

“You are strong, you have power, and at election time, that power will be through your vote. And you will tell them when they ask that you elected Joe Biden the President of the United States,” Harris said closing her remarks. “Thank you Fort Worth, and God bless Texas.”

Returning to the state for the first time since campaigning in the Iowa caucuses, Biden made his argument against Trump’s handling of COVID-19 directly to Iowan voters at a drive-in rally this afternoon, emphasizing the jobs lost in Iowa because of, he said, Trump’s unwillingness to deal with the pandemic. 

“Eighty-two thousand Iowa jobs lost in the pandemic, and still, they've not come back. Seventy-thousand jobs lost in Iowa since Donald Trump became president. Here at the fairgrounds, the Iowa State Fair cancelled for the first time since World War Two. Donald Trump has given up," Biden said to honking horns of support.

The former vice president repeated his campaign promise that he wouldn’t raise taxes on those making less than $400,000 a year, but said big corporations -- and the president -- will pay their “fair share” in a Biden administration. 

"Why should a firefighter, an educator, a nurse, a cop pay at a higher tax rate -- which you do -- than a major multi-billion dollar corporation? Why should you pay more taxes than Donald Trump, who paid $750?" Biden said, referring to a New York Times report. "Well, you ain't going to be gaming the system anymore in a Biden administration. They're going to start paying.”  

The race in Iowa is neck and neck with Trump leading by one point according to a Quinnipiac poll published Thursday -- remarkable given that Trump won the state back in 2016 by 10 points. 

While the state only has 6 electoral college votes, it holds a key demographic of Trump's base: farmers. And Biden catered his argument in Des Moines to that key base, arguing he can end trade abuses by China harming their industry, not Trump.

“He [Trump] says, because of, quote, his bailouts, ‘our farmers do better now than when they actually had a farm,’” Biden said. “Look, I'll do what he's been unable to do. I'll mobilize a true international effort to stop China's abuses, so we can strengthen manufacturing and farming in Iowa and across the country.”

In 2016, Trump’s strength in rural counties propelled his victory in Iowa, which saw the largest swing away from Democrats among the six states that flipped from former President Barack Obama to Trump. But Biden also made clear his close relationship to Obama, reminding Iowans they led them to the White House in 2008 and 2012. 

"You, too, have a sacred duty -- a duty to vote. It matters," Biden said. "Iowa matters."

Wisconsin Department of Health Services told ABC News that a total of five cases have been linked to four different Trump rallies over the last three months.

Here's how the cases breakdown: One case from Oshkosh Trump rally on Aug. 17; One case from Mosinee Trump rally on Sept. 17; Two cases from Janesville Trump rally on Oct. 17; One case from Waukesha Trump rally on Oct. 24

In addition, the health department has identified one case linked to a Biden campaign rally in Manitowoc on Sept. 21.

As ABC News has previously reported, in Minnesota, at least 23 cases have been linked to coronavirus outbreaks from three Trump/Pence campaign rallies in September, and North Carolina on Thursday announced that two people who attended a Trump rally in Gaston County on Oct. 21 have tested positive.

However, Wisconsin Health Services Department cautioned that the above cases from Wisconsin "don't necessarily provide a complete picture."

"Because of the sheer volume they’re working with, our contact tracers are conducting abbreviated versions of full interviews and may not capture all details about where an infection was acquired," Wisconsin health department spokesperson Elizabeth Goodsitt told ABC News. "Also, the people below reported other possible exposures, so we can’t say for sure these events were or were not the cause of these cases."

Departing the White House for a three-state tour of Michigan, Wisconsin and Minnesota, the president aired his grievances with Minnesota's coronavirus measures imposed by the state's Democratic governor which will restrict his rally size -- for the first time -- to 250 people, while arguing he has "biggest crowds in the history of politics."

"We have 25,000 people in Minnesota, which is our last stop today. Twenty-five thousand people want to be there, and they say you can only have 250 people. So they thought I’d cancel, but I'm not canceling," Trump said, adding his supporters are still angry from civil unrest over the summer.

"And I think it's going to flip for the first time since 1972," Trump added.

After losing Minnesota to Hillary Clinton by just 44,000 votes in 2016, Trump has set his sights on flipping the historically blue state, which has not voted for a Republican presidential candidate since 1972. His visit on Friday will be his fourth trip to the state this year and his eighth visit in the last four years.

But Trump is also facing a surging coronavirus pandemic in the Midwest, as Minnesota state health protocols currently mandate that all large gatherings be limited to 250 people, which the Trump campaign has deemed "free speech-stifling" ahead of the president touching down in Rochester. 

Trump narrowly lost Olmsted County, which includes the city of Rochester, by 598 votes in 2016. Although once a fundamentally Republican area, Obama carried the county twice, and now the Trump campaign has devoted increased resources into flipping such districts and courting voters in surrounding rural communities.

The former vice president is set to appear at a drive-in campaign event in St. Paul -- where Democrats have historically performed well -- just one hour before the president is scheduled to appear to take the stage an hour south.

The candidates' visits come one day after the state's reported its single highest daily increase on record. They also come on the heels of the the Eighth Circuit Court of Appeals' decision to require all absentee ballots in Minnesota to be received by local officials 8 p.m. on Nov. 3 in order to be counted -- a victory for Trump who has demanded all votes be tabulated on election night, though votes are always certified in the coming days and weeks.

FiveThirtyEight's polling average currently has Biden leading in Minnesota by 8 points.
