Last week we took note of a Washington Post poll that seemed to indicate support for the Birther movement collapsing, following President Obama’s release of his “long form” Hawaiian birth certificate. But there’s another poll from Zogby that didn’t get as much media play, also taken after the release of Obama’s birth certificate, and it shows something very different: 30% of Republicans Continue to Believe Obama Not Born in US.

UTICA, NY - 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%).
