If you think what Trump said was bad, here are a couple gems from May 2008:

Hillary Clinton - “My husband did not wrap up the nomination in 1992 until he won the California primary somewhere in the middle of June, right?” she said. “We all remember Bobby Kennedy was assassinated in June in California.”

Joe Biden - “I’ve got two [guns], and if he tries to fool with my Beretta, he’s got a problem,” he said in reference to Obama.
