30% Of Republicans Remain Birthers

Even after the release of his long-form birth certificate, 30% of polled Republicans say they don't believe the president is a U.S. citizen.

Sixteen percent of all voters and 30% of Republicans do not believe President Barack Obama has proven he was born in the U.S., even after release of his long-form birth certificate, a new IBOPE Zogby interactive survey finds. These results are from an IBOPE Zogby interactive poll conducted April 29-May 2, which was after Obama released the birth certificate and addressed the news media on the topic. Demographic groups besides Republicans expressing the highest levels of doubt about Obama's birth in the U.S. are conservatives (34%), and those without a college degree (21%) vs. those with a degree (11%).
