You can write in. It becomes a question of voting for someone you think can win and do a little vs. someone whose platform you actually agree with. I'm writing in Kucinich or Edwards in the primary, and if Nader runs, I'll seriously consider voting for him.

Either of them is better than the current occupant of 1600 Pennsylvania Ave, right? And whoever gets elected isn't going to be able to make dramatic change, that's the nature of the checks-and-balances system. But I had sorta hoped that someone who wasn't such a friend of corporate handouts and the military-industrial complex would be elected.
