I don't want to make you to optimistic, but you know that in the scholastic poll of High Schoolers, kids voted Bush over Kerry right?
In 4 years, all those kids were be allowed to vote.
I know--there are alot of high schoolers who will vote in four years--and many are conservative and will vote against their parents. In spite of the fact that young people seem to have a low turnout rate, I suspect that conservative young people are more committed about voting (as well as any other responsibility) than are liberal kids.
