Is it possible Bush 43 would even tried to seek a 3rd term in 2008 ?
No, his approval ratings were hovering around Nixon and Carter levels. I wanted to keep the scenarios somewhat realistic, which is why I also omitted Truman. I stand by my original claim that the only realistic 3rd term possibilities if the 22nd amendment was never passed are Eisenhower, Reagan, and Clinton. And while none of them were sure victors, they at least had high approval ratings when they left. It's unrealistic to think of Bush winning in 2008.
