Here's the results of a PPP poll of Republican voters planning to participate in the Illinois primary -- you know, the state where President Obama was a resident, state senator and U.S. Senator.
Do you think Barack Obama is a Christian or a Muslim, or are you not sure?
Not sure: 37
Do you think Barack Obama was born in the United States, or not?
Was born in U.S.: 36
Not born in U.S.: 36
Not sure: 28
Do you believe in evolution, or not?
Believe in evolution: 41
Do not: 43
Not sure: 16
Incidentally, minor wording gripe. One doesn't "believe in" evolution. Belief implies faith. We either accept the scientific facts or we don't.
Regardless, the "not sure" numbers are almost more ridiculous than the people who think the president isn't American, etc. I assure you, there would never be "not sure" numbers as high as this for a white president.
