Not a chance. I think Jeb is probably the most conservative of the group, but there's no way the voters will tolerate another Bush for awhile. He's going to wait till '12 or '16 before dipping his foot in that water.
More like '16 or '20 or even'24. I don't think 2012 is far enough into the future. It's only four years after W leaves office. If Hillary gets elected in 2008, people will be ready for another Bush in 2016. If Jeb were elected in 2016 and served two terms, he would be out of office in 2025. Fortunately Chelsea Clinton would not be eligible to become President, because her birthday was on February 29, 1980, and she would be just 40 days shy of the minimum age of 35.
