Nobody cares anymore. He's smart to not even go down that road ever again. They are trying to bait and bring him down
Why shouldn't he be held accountable for his original political lie that catapulted him into the political spotlight?
None of his supporters care.
Save it for if and when he gets the GOP nomination.
Then it will be perfectly appropriate to point out that the Trump is a Birther.
It baffles me why his "supporters" wouldn't care. Do they like chronic liars?
Two reasons
First of all- lots of Trump supporters love his implied ethnic attacks and assume he is every bit as much of a racist as they are and
Second- and most of all- Trump supporters don't care what he says. Truth- Fiction-doesn't matter- as long as he keeps making noises from his mouth they will support him.
