There is an amendment to the U.S. constitution that requires the President to be a natural born citizen, so Obama had to produce a birth certificate that shows he was born in the U.S. and this would have been checked against the hospital record to ensure it was not a forgery before he would have been allowed to run for President. Why is that simple concept so difficult for people to grasp?
Can you cite anything that says a candidate must display his birth certificate prior to running?
Once the committee decides the waters are warm, it's time to file a Statement of Candidacy. This includes the candidate's name and address, the name and address of his or her principal campaign committee, and little else. Technically, you don't need to fill out the paperwork until you've raised or spent $5,000 on your campaign; after that, you have 15 days to send the form to the FEC and the opposing candidates. A candidate gets another 10 days to fill out a Statement of Organization, which registers his or her principal campaign committee with the FEC. The document designates a treasurer and a custodian of records to oversee money in and money out.
