If there are two guys in the GOP field who really don't seem to care for each other, it's Jeb Bush and Donald Trump. Trump labelled Bush a "low energy" person who "doesn't really want to be doing what he's doing" and Bush has referred to Trump as a "clown," a "buffoon," and an "@$$hole." Given the animosity between them, it's probably not surprising that the last 24 hours has seen the launch of two attack ads - one from each side.
