According to a new Public Policy Poll released this week, more than half of likely GOP Primary voters are still wary of President Obama’s citizen status, questioning his birth certificate. The doubting demographic are commonly known as “birthers”, and out of 400 people surveyed between February 11th and February 13th, a little over half said that they still had questions about President Obama’s American citizenship. 28 percent of that same group of people said that they believe that President Obama was born in the US, and another 21 percent said that they weren’t sure either way.
