Charlie Cook sees the tide possibly turning on the president’s approval ratings (in National Journal, requires free sign-up). He writes, in part:

While the difference between 11 out of 12 under 40 — averaging 37.5 percent — and three in a row just over 40 — averaging 41 percent — is not sufficient to declare that something is happening, it’s a tip off that at the very least, Bush has stabilized his situation, at least temporarily, and recouped a bit of lost ground.
