“harping on this issue ( especially Obama’s birth certificate, which I personally think is irrelevant )”
We could tell that already, by your use of the word “harping”...
It’s obvious and clear what it means. It means born a citizen, not a naturalized citizen. That’s why McBain can’t be president, but his kids could. Everyone knows that.
What were the circumstances behind McCain’s birth that disqualifies him?
sorry - McBain = easier to type than Schwarzenegger.
