Read his lips: Gov. Jeb Bush (search) really, really isn't interested in succeeding his brother in the White House in 2008.

Bush reiterated Tuesday that he is not going to run for the Senate when Florida has a seat up in 2006, and said he has no designs on the presidency four years from now.

And he is getting awful tired of the question.

"Might you change your mind?" asked a reporter.

"No!" governor said. "Why am I not believable on this subject? This is driving me nuts."

But he dodged a question on whether he might "eventually" run for president.

"Eventually, what's that?" Bush asked after a sigh.

The governor's second and final four-year term ends in January 2007.
