During the course of the 2016 elections, then-candidate Donald Trump came up with a nickname for each of his opponents, and none of them nice. As 2020 approaches you can bet he’s going to start making new ones for all the Democratic candidates currently moving in for a shot at the Oval Office.

It would appear that Trump is fashioning a nickname for what is, so far, his biggest threat. Taking to Twitter on Monday, Trump commented on a speech former VP Joe Biden gave over the weekend, where he got a bit tongue-tied on stage. Of course, Trump immediately launched into making fun of him for it.

“Joe Biden got tongue tied over the weekend when he was unable to properly deliver a very simple line about his decision to run for President. Get used to it, another low I.Q. individual!” tweeted Trump.

If I were a betting man, I’d say “low I.Q. Biden” is a phrase we’re going to start hearing him say quite a bit in the near future.

Biden could take this a sign of some sort. According to poll after poll, Democrats consistently think Biden is the man to lead the left against Trump’s increasingly united Republican party. Trump may be trying to trip up his campaign before it even gets started.

Although, Trump may not have to work that hard. Many within the Democratic party seem to have a problem with Biden being up front. Some believe he’s too moderate, some believe his time is passed, and others believe that after elected a black man for President and then nominating a woman, Biden is too male and white.
