I'll never forgot when, in my first political science college class, my professor (who refuses to identify his political alignment, but I'd guess is a liberteraine) was raging about the ridiculous standards Americans put on their presidents... what they demand their presidents give them, and what they DON'T demand. The economy was a red herring for politicians.
"I mean, honestly, do people really think the president has a big lever in his office that he uses to point to "good economy" when he's gotten some and "bad economy" when the wife makes him sleep on the couch?"
