Care to add any? Also, if I'm wrong on a few, I apologize. Let me know.

Update:

A few mistakes to correct (thanks commenters!). I have removed Gary Cooper (he's dead and I have no idea how he got on there), Rob Lowe (he's only a Democrat who supported the Iraq invasion, although not necessarily Bush), Brad Pitt (same as Lowe), and Trey Parker and Matt Stone (since they have not come out officially for Bush and are hardcore libertarians, saying "We hate conservatives, but we really f*cking hate liberals.")

I have also added Ben Browder, Adam Sandler, Stephen Baldwin, and Freddie Prinze, Jr.

To clarify, John Travolta is an air and space fanatic (hooah!), and did state that if Bush realigns NASA to go back to the moon and to Mars, it would count as a vote. That is why he is on this list.

As for the various female celebrities, particularly the models, they are on the list either because they have made pro-Bush statements or have appeared doing pro-Bush activities.

Also, issues have been raised concerning the musicians on this list. I should not have added them since they are not traditional celebrities, but I will keep them on the list anyways for future reference.

And, of course, this list is by no means conclusive and probably a few up there should not still be on the list. If you find any, please let us know by posting a comment in the Open Thread on the top right corner of the Gene Expression homepage.

Update 2:
I have added Reba MacEntire and Robert Davi.

Update 3:
I have added Richard Petty, Jean-Claude Van Damme, Ricky Schroder, Connie Stevens, Kirk Cameron, Pat Boone, and Andy Garcia. I will cease updating this at this point, considering that a much longer and extensive list is located at Wikipedia.
