Blackburn Down With Birther Bill

This is, well, it is what is, I suppose: U.S. Rep. Marsha Blackburn is one of six Republican sponsors of a bill that would require future presidential candidates to show their birth certificates to establish they meet the Constitutional requirements to serve.

The bill, introduced in March by U.S. Rep. Bill Posey, R-Fla., received Blackburn's endorsement last Friday as Congress left for its 4th of July recess.
