Joe Biden has won the Florida, Arizona and Illinois Democratic primaries, giving him what is increasingly becoming an insurmountable delegate lead over Bernie Sanders.

Why it matters: The contests on Tuesday marked the first round of state primaries since President Trump declared a state of emergency over the coronavirus pandemic. Sanders and Biden have canceled rallies and traditional outreach efforts in order to stop the spread of the virus.

  • Biden is projected to win all three states as of 11pm ET Tuesday. Sanders, who is facing calls to drop out, did not address the press or his supporters on Tuesday night.
  • Ohio was also set to vote Tuesday, but Gov. Mike DeWine stepped in and ordered the closure of polling sites, citing a public health emergency. He is seeking to delay in-person voting to June 2.

Our thought bubble: Sanders has continually lost states where a majority of Democratic voters supported Medicare for All.

  • And if you can’t win places like Florida and Illinois, what’s the case for the general election?

The bottom line: The coronavirus has been smothering Sanders’ already difficult path to a comeback. 

  • The Bernie movement was built on massive rally crowds and huge canvassing efforts, all of which have come to a grinding halt with social distancing. 
  • Sanders' chance to make his case on TV and social media has been crowded out by the public and media focus on the virus. For example, cable networks broke away from their primary coverage last night to discuss the virus.

Biden was projected to win the state within minutes of polls closing. The state's final precincts closed at 8pm ET.

  • 219 delegates are up for grabs.

Scoop: How the White House is trying to trap leakers

President Trump's chief of staff, Mark Meadows, has told several White House staffers he's fed specific nuggets of information to suspected leakers to see if they pass them on to reporters — a trap that would confirm his suspicions. "Meadows told me he was doing that," said one former White House official. "I don't know if it ever worked."

Why it matters: This hunt for leakers has put some White House staffers on edge, with multiple officials telling Axios that Meadows has been unusually vocal about his tactics. So far, he's caught only one person, for a minor leak.

At least 11 Republican congressional nominees have publicly supported or defended the QAnon conspiracy theory movement or some of its tenets — and more aligned with the movement may still find a way onto ballots this year.

Why it matters: Their progress shows how a fringe online forum built on unsubstantiated claims and flagged as a threat by the FBI is seeking a foothold in the U.S. political mainstream.
