I doubt that. In fact, he's probably got a FICO score near 800.
The question is whether President Obama's actions / words / policies are why we've been downgraded and might be again. So let's parse ...
When were we downgraded last, and why? Because of the little game of chicken Boehner was playing with the debt ceiling increase, which previously passed, easily and with little fanfare. So what happened? Moody's feared an unwillingness on the part of the US to service our debt, and new borrowing became more questionable. It's not an ability thing; indeed we are the richest nation on mother earth, by a wide margin. We've handled debt in that past, with similar debt to GDP. The only concern is our Tea-infused House of Reps, getting all retarded and shit and diminishing the preceived strength of "Full faith and credit of the United States."
And even when they veer off at the last second, the Boehner retards don't veer off by much. They just kick it down the road 3 or so more months. So of course that damages our credit worthiness.
Japan has higher debt to GDP, and a better credit rating. Why is that? Obviously, they do not have abject ******* retards like we do, vis a vis the many Tea Party nincumpoops whose dicks Boehner is sucking.
So it continues: a poorly veiled attempt to sabotage this country, so Boehner & Co can blame Obama for shit going south, or at least north too slowly. And while I'm not so foolish as to think the braindead Cons who litter this site will ever get it, many voters are. The typical voter is totally fed up with this stupid ******* game Reps are playing, and the opinion polls show it, unambiguously.
So, **** you, Republicans. You deserve where you've climbed to get: the ******* bottom.
