Don't forget Al "I invented the Internet" Gore. What actually happened was: Al Gore as a young senator was shown ARPANET, the precursor to the Internet. He then wrote the High Performance Computing Act of 1991 which led to the creation of the Internet as we know it today. During the 2000 presidential election cycle, he gave an interview in which he stated that he "took the initiative in creating the Internet" -- a perfectly reasonable claim that went unremarked upon at the time. Months later, Bush advisor Karl Rove dug up the interview and orchestrated a smear campaign through which Gore was supposed to have claimed to have "invented the Internet" and the rest is history.

Democrats do not sabotage their careers by yelling weirdly or being photographed with their tiny heads sticking out of tanks. They are assassinated (just politically, usually) by a savage and ruthless enemy.
