Pretty sure Edison invented the motion picture and phonograph. Edison is freaking brilliant (no pun intended) Marty is a stupid hockey player. Voting for Marty is akin to voting for Bon Jovi.
Hard to argue against that really. Then again, the other semifinal is Bon Jovi vs. Woodrow Wilson. I'm not a Bon Jovi fan really but if I vote for "It's My Life" over the Federal Reserve Act am I being ignorant/immature?
