Since 2000 there have been several black and white issues for people to decide how they feel about Bush (which in 2000, there weren't). There were people voting for Bush in 2000 who didn't know how they felt about either candidate.
I don't even think many people have decided how they are even going to vote yet. The 2004 election will be interesting, to say the least.
