Trump is talking to birthers who were talking like this before he arrived on the scene...this crap from the birthers began immediately after the black man walked into the white house and was to continue until the '12 election. The Donald is riding the birther wave for publicity, and the media is more than willing to oblige him...the GOP organization has made no effort/will make no effort to marginalize Trump - he serves their purpose.
Don't complain for what you don't have - be thankful you don't get what you deserve. Irish Proverb
