From Holden:
What follows is a limited list of the current job approval ratings for George W. Bush that happen to be his all-time low ratings for the respective polls. There may be other current all-time lows out there that I’m missing, but here are the six I can verify.
Rasmussen: 38%
American Research Group (ARG): 34%
CNN: 32%
Fox News: 33%
Gallup: 36%
