Who's Nader?

I would have preferred the US citizens to have voted for the lesser evil tbh.
I feel a lot of people that could have prevented Bush from becoming a president are not happy with either, and haven't voted at all, in protest.
When will people learn not voting out of protest doesn't work?
People say Kerry has an anti-policy.
Whether or not that is true, I have to admit I don't know, but being anti-Bush, and in my belief that a lot of other people, including those who didn't vote 'out of protest', are also anti-Bush, I think Kerry was worth voting for just to see Bush not becoming a president.
