From Holden:

One of the many truisms I’ve heard bandied about during this campaign is that an incumbent never polls above his or her job approval rating.

If that is indeed true then Bush is dead meat. Here are the job approval numbers (with trends) for Bush for all polls conducted over the past week:

CBS News Poll

Approve 43 (-4)

Disapprove 48 (+5)

CNN/USA Today/Gallup Poll

Approve 47 (-3)

Disapprove 49 (+1)

Time Magazine

Approve 50 (-3)

Disapprove 46 (+3)

Associated Press-Ipsos poll

Approve 46 (-8)

Disapprove 53 (+7)
