It's hard to protest for places like Florida and Ohio when you're on the other coast, but you can try and get the word out to people that if someone tries to stop you from voting, then whip out your camera phone, take their picture and get their name. Document the shit out of it. That's probably the best way to fight it right now. Publicize it and let people in those states know to publicize it.
