Obama wants a good economy so he can get re-elected in 2012. That’s when he’ll have his fun.
He knows its a Republican program so eventually he will sign it knowing it is/will be a successful.
He won’t have his fun if he has a pubbie house and senate, which looks very likely. Obama’s days of supermajority fun are over, finito, caput. However, I don’t see him being re-elected anyway unless the economy makes a massive turnaround, very unlikely with him at the helm.
