At what point does Obama become responsible for his actions?

You mean like reversing the bush recession and pushing America into a recovery despite the best efforts of the Republicans and the tea party. Or like getting America out of Iraq and Afghanistan. Then there is that "killing bin Laden" thing. Or the record high Stock Market. Which action are you talking about.

Do you actually think the $ 2 trillion Bush blew on his totally unnecessary wars won't have any effect today? Its kind of like thinking Europe would just instantly bounce back from getting the heel bombed out of it in WW2. It took Europe decades to recover from WW2. It will take the US decades to recover from the damage Bush did. The bills from his unnecessary wars will be coming in for decades. Decades. I only wish the irresponsible reckless foolish people who voted him into office would be the ones to pay for the damage their stupid votes did. I can't think of a single reason why people who voted wisely, for Gore and Kerry, should have to pay to clean up the mess made by the idiots who voted for Bush.

He is. He owns up to everything.

But when are Bush & Cheney going to be held accountable for their actions?

Pretty much never unless it is something like getting obl which he had little to do with.

Never. People like him do their damage and then moon walk of the scene without ever accepting any consequences.

Socialists are never responsible.
