In it, but not of it. TPM DC

Poll: 48% Of Iowa Republicans Say Obama Wasn't Born In U.S.


However, the high birther base does not necessarily mean that the issue will be critical in determining which candidate wins Iowa. Donald Trump, who has vaulted to the front of several polls through a media blitz in which he's repeatedly questioned Obama's birth, placed a modest third in the poll's hypothetical primary election. While 19% of voters who doubted Obama's citizenship backed Trump, 25% broke for Huckabee.

The PPP poll was conducted April 15-17 among 419 registered Republican voters. It has a margin of error of 4.8%.
