Despite the birthers' best efforts, Americans believe by 77 percent to 11 percent that President Obama was, in fact, born in the U.S., according to a Daily Kos/Research 2000 poll conducted July 27-30. Twelve percent were not sure.
The group of biggest doubters were Republicans who agreed that Obama was U.S.-born by a lesser 42 percent to 28 percent with 30 percent not sure. Independents acknowledged Obama's native birth by 83 percent and Democrats by 93 percent.
Regionally, the part of the country with the most doubts was the South where 47 percent said Obama was native-born while 23 percent said he was not and 30 percent were unsure. Americans in all other regions said Obama was native-born by 87 percent or more.
