John McCain physically attacked fellow congressman. Called his wife a CUNT

In 2006, the Arizona Republican congressional delegation had a strategy meeting. McCain repeatedly addressed two new members, congressmen Trent Franks and Rick Renzi, as 'boy.' Finally, Renzi, a former college linebacker, rose from his chair and said to McCain, "You call me that one more time and I'll kick your old ass." McCain lunged at Renzi, punches were thrown, and the two had to be physically separated. After they went to their separate offices, McCain called Renzi and demanded an apology. Renzi refused.

What an asshole.

In his 1992 Senate bid, McCain was joined on the campaign trail by his wife, Cindy, as well as campaign aide Doug Cole and consultant Wes Gullett. At one point, Cindy playfully twirled McCain's hair and said, "You're getting a little thin up there." McCain's face reddened, and he responded, "At least I don't plaster on the makeup like a trollop, you cunt."
