It’s not like it’s enforced. Lots of non-natural born citizens have been allowed to run for president. Off the top of my head in my lifetime, George Romney, John McCain, Barry Soetoro, Ted Cruz.
A little research adds Chester Arthur, Christopher Schürmann, Lowell Weicker, Charles Evans Hughes, Marco Rubio and Bobby Jindal.
The secretaries of state, in all states, should enforce eligibility requirements on their respective ballots.
As much as I don’t like McCain, I think that if both parents are US citizens, and are overseas while in service to the US Government (maybe restrict it to military) (in the case of McCain, his father was stationed at the Panama Canal Zone serving the US Navy), the natural born requirement should be met.
In the case of Obama, his father (assuming it’s Obama Sr, not Frank Marshal Davis) was a British subject, thus only one parent was a US Citizen. Plus Obama’s stay in Indonesia brings his citizenship into question as well (did Stanley Dunham renounce her US citizenship while in Indonesia). Thus Obama’s occupation of the White House was clearly in violation of the Constitution.
Pres Chester Arthur?
Never heard such a thing. And the Wiki seems to cover it as just a malicious rumor, whether Ireland or Canada.
My only question would be his father’s citizenship status.
