Well, you're right. People sure do blow hot and cold around here. Even the most rabid of Bush supporters turn on him in a second if he ever puts the mildest pressure on Sharon. Of course, when Sharon says "We're going to withdraw from Gaza" they turn on him too. I don't know who is far enough to the right for some folks.
As far as Gibson having doubts about Bush, who doesn't, after the steel tariffs, increased funding for NPR, ever rising budgets, his administration's use of ad hoc intelligence teams to tell him what he wants to hear, his failure to plan adequately for post-War Iraq, and the ever-encroaching police state under the Patriot Act I & II? Having said all that, Kerry would still be worse. He wants new hate crime laws to make it a criminal offense to hurt someone's feelings (even if you're only telling them the truth).
