Nothing will come of it. He is just messing with Obama cuz the feds keep messing with him.
The Sheriff just needs to state what the truth is and it will disqualify Obama. The passport with him being striked out for loss of citizenship is probably enough. If he can get someone from INS to verify that that was the process, then we in fact have a president who lived as a foreign national. People can choose to ignore it, but with gas going to 5 dollars a gallon in our fancy new communist country, good luck.
