WaPo columnist, Jennifer Rubin:

It took less than 4 1/2 years of the Obama presidency for President George W. Bush to mount his comeback. While doing absolutely nothing on his own behalf (he’s been the most silent ex-president in my lifetime), his approval is up to 47 percent according to The Post/ABC poll. That’s up 14 points from his final poll in office.

Well, sure.  Even my approval of George Bush goes up when he is silent and does nothing.
