Quite a bit of that "wrong track" rating might have been conservatives fearful that John Kerry was winning. The positive polling numbers seem to have increased markedly since the election.
Half the "wrong-trackers" think Bush is a leftist.
Likely you've got something there. In any case, that "right track/wrong track" question strikes me as the silliest I've ever heard. There are too many "tracks" going on at once, with too much divergence by state or city. Not to mention the question of who's more likely to slow down or turn around the "wrong track" areas and encourage the "right track" ones. The range of possibilities in how people will understand the question make any total of the answers meaningless.
