Unless I misread the situation, demokkkrats have zero economic credentials. Demokkkratic support is due to the bad taste re: the war in Iraq and a "our nation is evil, let the healing begin" sentiment.
The other problem is obummer being a small target and putting NO solid policies up. The "change & hope" number will wear thin. He can't keep it up 'til November.
With any luck,by November, obummer will release a policy or two that frighten the middle class, like higher taxes or more immigrants.
