I think Trump already has researched the issue. He knows Hussein cannot produce a birth certificate. People have a right to ask WHY ? He is President of the United States.
I hope you are right. Given that, the Repub national committee should focus exclusively on gettting the state legislators of Florida to pass a law requiring a legitimate birth certificate, proof of natural born citzenship and a public release of such information to be put on the 2012 presidential ballot. Florida's Houses and governor are Republican, and also Florida is a huge swing state. Obama, practically, has to win Florida in order to win the presidential election. Or else, he will have a terrrible uphill battle.
If BHO does not produce such documents, he does not get on the ballot and by default, loses the sunshine state. IOW, he must put up or shut up-or as they say in chess, "Check".
