"The use of fake documents by the Obama campaign should send up all kinds of red flags. He wouldn't have this out there if the alternative were harmless."

That's the first intelligent comment on this thread. If it were genuine, the certificate number would not be blanked out. There are only two possibilities here:
1. Its an erased and re printed certificate from another individual. or,
2. Its a blank that was furnished by one of the Obama flaks in the county clerk's office, that would not have a number in any field.

Either way, he's not a citizen, by neither birth, nor by application for citizenship, and thus is not elligible to hold public office. Any Senate vote where his vote was the deciding edge is therefore invalid.
