Hi Rip,
Sadly it really doesn't matter. The jobless rate could fall to 1% and be made up entirely of the congenitally unemployable and it still wouldn't help the administration a bit. No administration, no matter how successful, could survive long in the current climate. In politics, perception, not reality, is everything. As long as you are perceived favorably, you are doing well. The current administration will never be perceived favorably, they have the academy, the intelligentsia, the press, Hollywood, and now most of the government constantly churning out negative information about them on a constant basis. For instance, today NPR greeted the positive employment news with several pieces on unemployment amongst minorities and how the government doesn't care. This was followed by a piece about how the figures themselves can still be interpreted in a way that makes them less cheery.
The fact that if the figures had come out during the tenure of Bill Clinton they would have been greeted with unanimous front page tub-thumping approval is never considered. With Bush, no news is ever or can be good news. And when the news is negative, there is literally no bottom to how bad it can be. We have gotten to the point where the President can be blamed, for instance, not only for the results of a Hurricane, but for the Hurricane itself. At one time a reporter who took that line would have been considered a crazed moonbat political hack, going beyond even the vitriol heaped on American presidents by say, Pravda. Today, that kind of thing is mainstream and thoroughly passe.
It seems to me that while conservatives may have won the cold-war against the Soviets, they have lost the war against socialism at home and abroad. Conservatism as a western political viewpoint is simply viewed as evil, heartless, and incapable of producing any kind of good in most of the world. Generations now have been raised to think that, and it isn't changing. Given enough time, it will be as unpopular to say "I'm a conservative" as it is to say "I'm a Nazi." I've spent time in places where most people already think they're synonyms.
