Regardless of which party did what or signed which bills isn't the point. The person in charge is not supposed to sit back and let things happen.
Consider the way Bush pushed the Iraq war. He was on TV frequently enough to have his own show. If he knew a financial crisis was coming and he should have known he should have advocated for action as vigorously as he did for the war.
Something as serious as the financial crisis required him to demand Congress make whatever changes are necessary even if he had to go on TV every night, all night long. His responsibility as the leader was to do everything in his power to stop it from happening. That's where he failed.
He convinced people the war was a necessity when it wasn't but he never tried to convince the people there was a financial crisis looming and there was.
As for interrupting just jump on me and sit ..........
