Indeed he was, but much like many of Hawaiian-born Barack Obama's political opponents tried to float the "born in Kenya" myth, many of Arthur's political opponents tried to float the "born in Canada" myth.
The citizenship of Arthur's father never factored in to anything. Why? Because the citizenship of one's parents has no bearing on their natural born status if they were born in the United States. Not President Arthur's Not President Obama's and it won't for Senator Rubio when he throws his hat into the ring. Nothing but birther nonsense that gets laughed out of every courtroom every single time.
Nobody of any importance is buying this crap. It is the abode of unhinged crackpots and, like Donofrio, conspiracy nuts.
