No more questions about whether Biden will run. He's in! Via the New York Times:

WASHINGTON — President Biden formally announced on Tuesday that he would seek a second term, arguing that American democracy still faces a profound threat from former President Donald J. Trump as he set up the possibility of a climactic rematch between the two next year.

In a video flashing images of a mob of Trump supporters storming the Capitol on Jan. 6, 2021, the president said that the “fight for our democracy” has “been the work of my first term” but is incomplete while his predecessor mounts a comeback campaign for his old office that Mr. Biden suggested would endanger fundamental rights.

“Around the country, MAGA extremists are lining up to take on those bedrock freedoms away,” Mr. Biden said, using Mr. Trump’s Make America Great Again slogan to describe the former president’s allies. “Cutting Social Security that you’ve paid for your entire life while cutting taxes for the very wealthy. Dictating what health care decisions women can make, banning books and telling people who they can love. All while making it more difficult for you to be able to vote.

“When I ran for president four years ago,” he added, “I said we were in a battle for the soul of America. And we still are.”
