I'm interested to know why you think this given Congress is currently controlled by Democrats.
I couldn't offer more than election results.
Election results? I don't get that, unless you're going on the historical fact that a President loses Congress in his second term. If that's the case, you're way ahead of the game, IMO. Obama's only 60 days into his first term and if he doesn't turn some things around, he's going to be toast.
But yes, it "could" happen. If it happens, as I said, it will depend on the reason. Your argument however assumes I am going to take a partisan line. As I said, it will depend on the reason whether or not I agree with it.
