A Bad Joke

A Democrat and a Republican walk into a bar. The bartender asks what they're drinking and when the bartender returns with their drink the Republican says, "Put it on my tab.", to which the bartender replies, "Hell, your credit card bounced and you haven't paid your tab from the 8 year party of the last Republican who was here." The bartender then turns to the Democrat who points at the Republican and says, "He's buying."
