One problem with this is that your vote really doesn't count. Unfortunately the republic structure of the United States voting system makes your vote important to the electoral college who in turn are supposed to represent you.

The only reason I can think of that might actually motivate people who actually advocate change through political process is that the Green Party is on the eve of getting some well deserved funding. Nader is not going to be president but at least his campaigning might well establish the Greens in the United States.

Then again, I'm pretty cynical about reformist politics in general. Bah humbug!
