Joe Biden is reportedly considering a presidential run. It was long rumored that his late son, Beau, wanted him to run, so it seemed only a matter of time before he took on the challenge. To say that Biden, 72, is gaffe-prone is to drastically understate his status as a loose canon. There was the time he inadvertently made the case against Barack Obama’s economic policies, or the time he advised just shooting a shotgun blast through the front door to scare away an intruder. And that’s not to mention his habit of practically groping young women. Hillary Clinton is vulnerable, and Biden might just mount a credible challenge. “I think that Biden would have a good chance at beating her now,” says Donald Trump. Which makes us think how much fun it would be to have a Trump-Biden debate. Imagine the possibilities.
