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.

Trump kicked off his rally in Waterford Township, Michigan, by commenting on the cold weather but saying he felt “very warm in this group” before confidently declaring, “Four days from now, we're going to win this state and we're going to go on to win four more great years in the White House.”

An ABC News/Washington Post [poll] () out this week shows Biden narrowly ahead of Trump among likely voters in Michigan, 51% to 44%.

Speaking to the packed crowd of mostly maskless supporters, Trump mocked the size of Biden’s crowds when compared with his, saying “nobody shows up.”

He also took aim at Biden's running mate, and though he regularly mispronounces Kamala Harris’ name, Trump added the false claim that Harris can't pronounce her own name either.

At one point the president called out to Fox News’ Laura Ingraham, who was present and expressed disbelief that she was wearing a mask -- though coronavirus cases are rising in Michigan and nearly every other battleground state.

"Where is Laura? Where is she? I can't recognize you. Is that a mask? No way. Are you wearing a mask? I've never seen her in a mask. Look at you. She's being very politically correct. Whoa!" Trump said.

Ahead of more rallies in Wisconsin and Minnesota, Trump complained that local officials in Minnesota are “scamming” him by not allowing his campaign to hold a rally of more than 250 people in order to adhere to the state's COVID-19 restrictions.

“You know what, that maybe will give us the final victory. We haven't won Minnesota since 1972, OK?" Trump said. "That's not good odds, but we are very popular because I helped with that disaster in Minneapolis."
