I believe Bush will be getting a lot of the younger vote. There are a lot of LIBERAL campus activists and they always get a lot of LIBERAL media coverage but students, young workers and parents are thinking ahead. This stretches across a wide spectrum, including jewish, black and hispanic voters. After 9-11 and the way Democrats have denounced Bush's liberation of Iraq, I wouldn't doubt the Left has even lost a lot of the senior vote.
Another hope I find, is that young people, being naturally inquisitive and rebellious, at least to some extent, and assuming that it hasn't been completely brainwashed or drugged out of them, will very likely recognize that something is amiss. Many will find themselves dissatisfied with what passes for intellectual and cultural nourishment and set out to find a better way.
