The disagreements between President Trump and former Vice President Joe Biden have escalated to threats of physical violence, with Trump tweeting Thursday that Biden "would go down fast and hard" in a fight. That followed a University of Miami event Tuesday, where Biden said he'd "beat the hell out of" the president if they were in high school together.

Why it matters: It's a preview of a potential 2020 slugfest — if Biden, who's been the subject of presidential speculation, decides to run. Not only is their rhetoric a perfect encapsulation of today's polarized political climate, but it also represents the sort of smash-mouth, off-the-cuff style of politicking that's fueled both politicians' popularity amongst their respective bases.
