It's happening the way it's supposed to happen. Voters are voting -- smashing records, adjusting behaviors and recalibrating expectations -- in ways that show the nation is many things, but definitely not apathetic.

It's also happening in ways that will stress the systems built to account for it all. More early votes, oddly, will mean reporting out results will take longer in several critical states -- to say nothing of the continuing challenges of participating in and administering an election in the midst of a pandemic.

Amid a flurry of COVID-era campaigning in battleground states, this week brought new high-water marks that suggest turnout records will fall this year.

Nearly as many Texans have voted as in all of 2016, with Georgia, North Carolina, Florida and Arizona are among the states already three-quarters of the way there, according to the United States Elections Project at the University of Florida.

But this week also brought continued uncertainties about the process of voting. The Supreme Court now has nine justices again, and voters in states, including Wisconsin, Michigan, Pennsylvania, Minnesota and North Carolina have a right to be confused about what the law is when it comes to how to vote -- and even what those laws might be on Election Day and beyond.

Layered on top of all of that are the efforts by President Trump to sow doubts about the integrity of the election.

From the local level on up, election officials say they're confident that there will be an accurate -- and, hopefully, promptly tallied -- vote count. But the surge of voting, while good for democracy, figures to make everything more difficult during this most difficult of times for the country.

Former Vice President Joe Biden wrapped up his campaign swing through the Midwest with a socially distant speech in front of just a few dozen people in an airport hanger in Milwaukee, a few hours after President Donald Trump stopped in the battleground state.

Biden remarked on the rising number of COVID-19 cases nationally and in Wisconsin specifically, which is facing one of the fastest-growing outbreaks of COVID-19 in the country, and repeated many familiar criticisms of Trump's handling of the pandemic throughout his remarks.

"I know it's hard. More than 225,000 people, I think it's 229[,000] as I speak, have already lost their lives to COVID-19. Two thousand here in Wisconsin. Six hundred here in Milwaukee County. This week, Wisconsin, like other states, set a new record for daily cases. Hospitals are running short on beds. Just had to open a field hospital. That's what we're facing," he said.

"Donald Trump waved the white flag, surrendered to the virus," he continued. "But the American people don't give up. We don't give in. Unlike Donald Trump, we're not gonna surrender to this virus. We are simply not going to surrender."

Biden also went after Trump on trade, calling his policy "a disaster" that "decimated" the Wisconsin dairy industry.

The candidate said his campaign is taking a different approach to Wisconsin than Hillary Clinton did in 2016.

"For a whole lot of reasons, not all of which were her fault, we ended up not taking it too seriously. We thought it was different," Biden said, adding, "I've been here a lot."

This marks Biden's third trip to Wisconsin since the Democratic National Convention, making it his fourth-most-visited state, behind Pennsylvania, Michigan and Florida.

Unlike Biden's drive-in rallies on Friday, his remarks in Wisconsin were given in an open-air airport hangar. The event was held at least partially outdoors on a near-freezing Wisconsin evening.

"I'll tell you what, they told me it's gonna be indoors. You're a hardy bunch in Milwaukee," Biden said.
