Bush's strategy contrasts with those of Clinton and Ronald Reagan, the last two-term presidents, who recovered from political troubles late in their tenures. Both found ways to work with an opposition Congress to pass important legislation. Reagan left office with a 64 percent approval rating and Clinton with a 65 percent rating.
He is truly the great divider.
In all seriousness though, this story is about how Bush's poll numbers haven't improved, but his political fortunes have. I think that is read "his political fortunes have improved among beltway insiders."
Isn't most of the turnaround due to the fact that everyone just ignores him now. The media is much more concerned about who the next president will be than what this one is currently doing to the country. It seems that for Bush, no news is good news.
