A new Gallup/USA Today poll finds significant doubt about whether Donald Trump, the real estate mogul and television personality who is considering a bid for presidency, was born in the United States. According to the survey, just 43 percent of Americans believe that Mr. Trump was definitely born in the United States. Another 20 percent believe that he was probably born here. Some 7 percent of respondents told Gallup that Mr. Trump was probably or definitely born in another country, while 30 percent were uncertain. No, this poll is not a joke. We’re several weeks past April Fools’ Day. But it’s one that should encourage us to proceed more cautiously when we see similar numbers reported for President Obama. There aren’t any good reasons to doubt that Mr. Trump, who has furnished a copy of his birth certificate, was born in the United States. Perhaps there are some bad reasons. Two of Mr. Trump’s three wives were foreign-born. And Mr. Trump was born in Queens. I don’t know if you’ve been to Queens, but it certainly ain’t Kansas. (Although it has much better food.) More... I have a grand idea here... how about only native North American's should be permitted to run for president in the future. Just remove the doubt completely. Only those that have ancestors living here in North America for thousands of years should run for president. I'd like to see "birthers" deny that.
