Has anyone heard exactly what political position Jeb is interested in? VP sounds like the very best choice. It has often been said that the VP does not effect a voters choice in electing a President. It would put Jeb in the position to run for the eventual Presidency. McCain sounds like the most likely choice. As much as we don't like him, he is pro life, very popular, and would beat the pants off of Hillary.
Let Harris run for Senate. The Bush dynasty would continue on and make political history..
Jeb has repeatedly said he has no interest in running for President in 2008, or for the Senate in 2006. He's only 51 years old, though, so he has plenty of opportunities later on down the line.
