I don't think the voters would vote for another Bush even if he WAS a great candidate. Americans have a thing against "dynastys".
Unfortunately, I think JEB is a great candidate. If GW had never run, JEB would have been a shoo in.
He is. Four years is a long time in politics. Americans will be tired of Hillary! regime and will look to Jeb as the only hope who can save them from her in 2012.
