Here's the ugly little truth about NBC. There's zero enforcement mechanism. The FEC has allowed clearly ineligible candidates to write a check and file since at least the 1970s.
Is it up to individual state secretaries to remove ineligible candidates? They haven't done so yet.
Or is it up to voters themselves to determine if a candidate meets constitutional eligibility requirements?
Bull shit! Where was your selective outrage when Bobby Jindal ran for President?
