Totally avoiding the question is a political move by Rush.
Rush, like most sane people, knows the question is meaningless. Obama will NEVER admit it, and what other proof do you have? Not much. The places that you may dig up proof is not talking.
Ok, so now you have a small amount of proof and take it to the SCOTUS. It is going to have to be OVERWHELMING proof from them to decide.
Now, the congress must toss the guy out.
We are talking years in a process that is meaningless and therefore lacks the need for ANY attention.
There fixed that!
