Iowa Poll: Many Republicans still doubt Obama was born in U.S.

DES MOINES — For years, businessman and media personality Donald Trump pushed the falsehood that President Obama wasn’t born in the United States.

He even sent investigators to Hawaii in 2011 to research the issue, and when Obama ultimately produced the long-form birth certificate, Trump claimed credit for forcing him to do so.

Now the front-runner in the Republican race to succeed Obama as president, Trump apparently remains unconvinced. When asked about Obama's provenance by CNN’s Anderson Cooper in July, he replied, "I don't know. I really don't know."

Turns out a majority of Iowa’s likely Republican caucusgoers — 59% — share Trump’s skepticism.

The new Des Moines Register/Bloomberg Politics Iowa Poll asked: “Do you believe Barack Obama was born in the United States or not?

Just 42% say yes, he was born in the U.S., with the remainder divided between those who express confidence he was not (35%) and those who do not know (24%).

Among Trump’s supporters, though, even more believe Obama wasn’t born in the U.S. (46%); 25% aren’t sure; and 29% say he was born in the U.S.

Democratic caucusgoers don’t share Republicans’ doubts: 91% say Obama was born in the U.S., 3% say not in the U.S. and 6% aren’t sure.
