Donald Trump just literally made the Republican race about his penis.

Over the last few days, Marco Rubio has gleefully picked up on a popular Graydon Carter line about Trump having small hands, not so subtly implying that Trump also has a small penis. In response, as my colleague Brian Beutler pointed out on Twitter, Trump once again turned the subtext of this race into text. 

After Rubio was asked about those personal attacks, Trump couldn’t contain himself. He held up his hands. “Look at these hands. If they’re small, something else must be small. I guarantee you there’s no problem. I guarantee you.” Like that, Trump turned this race into a literal dick-measuring contest. The Doomsday clock (which projects when Donald Trump will whip out his penis on national TV) is currently set at 11:59pm.
