My first instinct is that people will not accept another Bush as President (at least in the next dozen years or so) simply because of the dynasty thing. But Jeb is doing SO WELL.
I hope that by 2008 we have even more balanced media so that we can drown out the cries of "dynasty!" and people can hear what he's done. I think Jeb is purposely ignored by the media so as not to boost W.
