One who identifies himself as a Republican but cannot intelligently debate a single Republican issue.
The republitard generally believes that global warming is a left wing myth and that we have an endless supply of oil. He will frequently remark that George W. Bush is "smarter than he seems". The republitard has a bitter hatred of Hillary Clinton but is unable to cite a single reason why, except to say that she's just a bitch. Some of the more radical republitards actually believe that Bill and Hillary are serial killers.
