Playing the Republican Card/Plausible Deniability

President Obama is frequently compared by his harsher critics to Jimmy Carter. And, yeah, there are in fact some similarities; perceived and/or real ineffectiveness, major problems in the Middle-East, persistent difficulties with Congress (Mr. Carter's surprisingly more with his own party). But there is also one humongous difference. Obama can say (and President Carter couldn't) that he had to deal with a Republican Congress and that it was them who stymied his progress. Yes, it's possibly a stretch (this, in that Obama got a great deal of what he wanted early on and is also trying to take some credit for the lessened spending that those very same Republicans had forced him into) but, being that the Congress has an even lower approval rating (significantly, actually) than he does currently, I think that it's probably the most significant trump-card available to him.......And, so, yeah, he should use it.
