There's a frontrunner, who has led almost every national poll since last winter, allowing for a few outlier polls and a brief period around the end of the summer. There are three other leading contenders, two of whom have been near the top of the polls for months, while the third only recently emerged from the pack. There is a pack of dark-horse candidates, whose odds of being elected president now approach zero but who remain in the race for various reasons.  There are some with no shot at all. There are two fringe candidates, likely using this campaign to explore career options. And there's a pair of billionaires who hope to buy their way to the presidency by spending alarming amounts of money on campaign ads. That probably won't work — but you might have heard the same thing about another billionaire in that other party, a few years back.

Donald Trump snarled at his own FBI director on Tuesday morning after the law enforcement official backed the so-called "Horowitz report" -- breaking ranks with the president and Attorney General Bill Barr.

Taking to Twitter, Trump wrote: "I don’t know what report current Director of the FBI Christopher Wray was reading, but it sure wasn’t the one given to me. With that kind of attitude, he will never be able to fix the FBI, which is badly broken despite having some of the greatest men & women working there!"
