There are 2 must see docum. on voting Hacking Democracy and Uncounted. I just watched both again. Hacking is the more non partisan of the 2 but they both show scary things.

The thing that got me was in uncounted it looks like the software the one guy wrote to steal an election was used against him when he ran lol.. It was used in sourthern Florida and by touching 2 spots on the screen before you authenticated the votes it flipped them to the person you want to win..
