Behind the scenes, aides to President Trump have long seen Joe Biden as his biggest potential threat in 2020. Now, the president is saying it out loud.
Driving the news: "Looks to me like it’s going to be SleepyCreepy Joe over Crazy Bernie. Everyone else is fading fast!" Trump tweeted Friday. Trump also called Biden the frontrunner in an interview with Politico, mocking him for mistakenly referring to Theresa May as Margaret Thatcher: "Is that a good front runner? I don’t know. That was a beauty."
