Obama was President. At this point anybody born in the US as a citizen is eligible. That leaves Ted Cruz out but pretty much everybody else running the last couple of elections would be OK the way it is now.
That's like saying that a murderer who hasn't been caught yet isn't a murderer at all, even when there were witnesses to the act.
It’s getting to the point that, with all of these exotic and interesting individuals with so many different flavorful foreign backgrounds to choose from, regular old natural born citizens with pure vanilla American backgrounds (at most, perhaps their grandparents were once citizens of a foreign land), though competent, say, and inarguably eligible, are being drowned out by others deemed more exciting from a marketing standpoint.
Of course, if we had the capacity to behave more maturely and self-respectfully as a nation, those “others” would be forced down into the audience like the rest of us, not up on the debate stage reserved for actual POTUS-eligible candidates.
Let the word go forth. Let us declare expressly that the Command in chief of the U.S. Armed Forces shall not be given to, nor devolve on, any but a plain vanilla Citizen. Exotic flavors need not apply.
