John Thune is No. 4 in the GOP Senate leadership, and a serious VP or even POTUS candidate in 2012. He needs the party's support, so there's not a chance in Hades that he'll get involved in the BC issue.
Obambi will collapse on his own like Jimmy Carter did, based on bad economic policies and unconstitutional power grabs like HealthScare. Those are the issues on which he must be attacked. As Napoleon said, "never interfere when your enemy is self-destructing".
Probably not.
