Michael Bloomberg officially filed paperwork on Friday to enter the 2020 presidential primary in Alabama, though remains undecided on whether he will ultimately run, the New York Times reports.

Why it matters: The billionaire and well-connected moderate could pose a "grave and instantaneous threat" to Joe Biden, who is struggling to fundraise and has faced questions about his sharpness, per the Times.

The big picture: Bloomberg has been a long-standing "maybe" in the crowded Democratic field. But filing is a notable step, as is dispatching staff to Alabama to gather signatures for him to qualify for the ballot.

  • Alabama does not have an early primary, but the deadline to file for its ballot is Friday.
  • According to Alabama Democratic Party, Bloomberg also qualified for the Alabama primary Friday afternoon, per the Time

What they're saying: Bloomberg Foundation aide and Democratic political strategist Howard Wolfson posted on Twitter: "Mike believes that Donald Trump represents an unprecedented threat to our nation. In 2016, he spoke out at the Democratic Convention, warning against a Trump presidency."

  • "If Mike runs he would offer a new choice to Democrats built on a unique record running America’s biggest city, building a business from scratch and taking on some of America’s toughest challenges as a high-impact philanthropist," Wolfson added.

Why it matters: It’s nearly inevitable that the U.S. will still be dealing with the pandemic come January 2021, meaning voters in America will choose between two very different options for dealing with it.

The number of coronavirus cases increased in the vast majority of states over the last week, and decreased in only two states plus the District of Columbia.

Why it matters: This is a grim reminder that no part of the United States is safe from the virus. If states fail to contain their outbreaks, they could soon face exponential spread and overwhelmed health systems.
