However, its starting now and will only be a matter of time. "WASHINGTON (CNN) â Rep. Bill Posey, R-Florida, introduced legislation this week requiring candidates to produce a birth certificate to be eligible to run in future presidential elections, triggering a sharp reaction from Democrats who accused him of "questioning President Obama's citizenship." Posey submitted a bill with no fanfare Thursday that instructs the Federal Election Campaign Act of 1971 to be amended to add the birth certificate requirement. The Constitution requires that a president or a vice president be "a natural born citizen."
