Michigan Gov. Gretchen Whitmer (D) said in an interview with "Axios on HBO" Monday that she "can’t for the life of me understand" President Trump's antagonistic attitude toward her state, pointing out that he won it by more than 10,000 votes in the 2016 election.

The backdrop: Trump threatened to "hold up" unspecified federal funding to Michigan last week because the state government rolled out plans to expand voting-by-mail options amid the coronavirus pandemic. He's also repeatedly tweeted about Whitmer directly, claiming she's "way in over her head" with the coronavirus and that she "doesn't have a clue."

What she's saying:

"Why this antagonistic position against this state is something I can't for the life of me understand. And I would ask that we drop that. I was thinking the other day about when Barack Obama went into New Jersey after the hurricane, and was greeted by Chris Christie. And they both stood there and said we're going to get through this, we're going to work together. That's how it should be. And that's what I would like it to be like, frankly. And that's what we should expect it to be. And that's not what it is, obviously."

A bipartisan group of governors has joined the Rockefeller Foundation to deliver 3 million rapid coronavirus antigen tests to slow the spread of COVID-19 and help states safely reopen, the nonprofit announced Tuesday.

Why it matters: With no national plan, the initiative with Maryland Gov. Larry Hogan (R), Louisiana Gov. John Bel Edwards (D), Massachusetts Gov. Charlie Baker (R), Michigan Gov. Gretchen Whitmer (D), Ohio Gov. Mike DeWine (R), and Virginia Gov. Ralph Northam (D) would be the first coordinated testing strategy in the U.S.

Nevada Gov. Steve Sisolak (D) announced Monday evening that he's signed a bill enabling all registered voters in the state to vote by mail in November's elections.

Why it matters: President Trump told reporters Monday he'd sue Nevada in a bid to stop the mail-in measure. After Sisolak's announcement, Trump retweeted his earlier tweet stating: "In an illegal late night coup, Nevada's clubhouse Governor made it impossible for Republicans to win the state. Post Office could never handle the Traffic of Mail-In Votes without preparation. Using Covid to steal the state. See you in Court!"

The coronavirus will make the 2020 presidential election different from any in modern history: Voting that begins earlier, results that take longer, mail carriers as virtual poll workers and October Surprises that pop in September.

The big picture: Perhaps 80 million Americans will vote early, by mail or in person, Tom Bonier, CEO of TargetSmart, a Democratic political data firm, tells Axios. That's going to set up more of an Election Season than an Election Day — and increase the odds of national turmoil over the vote count.
