Hard to say....as pointed out many of the economic/employment issues are interrelated. His passed first major medicare changes in 20 years, no child left behind, major tax cuts at a critical time in a recession...could have been much worse per many economists. I think he would have a fighting chance.
One thing is clear...his opponent Kerry would still be a fraud. He is trying to sidestep a 20 year voting record left of the remained of even his own party, sidestep that he failed to vote most of the time, missed his committee meetings most of the time (no wonder he so good at 90 different leisure activities), horribly and almost single handedly hurt Vietnam Vet images here and abroad, and is absolutely without any rudder when it comes to holding a course on a position..
It was a gift for conservatives that Kerry was nominated. A more moderate candidate that had a spine may have taken the election. This could have been Lieberman's year (somewhat amazingly, given his Elmer Fud like resemblance). Now, I think dems are toast. The DNC convention killed him....emphasis ON his Vietnam record that was damaged bady by SBVets..emphasis OFF his voting record in the senate which Zel Miller just defined for him last night.
