President Obama apparently has his own birth certificate on his mind, literally.

“I can’t spend all of my time with my birth certificate plastered on my forehead,” Obama told Brian Williams in an interview last night on NBC’s Nightly News.

The remark was in reaction to a series of questions focusing on why a large percentage of Americans have serious doubts about the religious faith of the commander in chief, but Obama also took a shot a so-called “birthers” who want documented proof that Obama is a “natural-born citizen” and thus constitutionally eligible to hold the presidency.

“The facts are the facts. We went through some of this during the campaign – there is a mechanism, a network of misinformation that in a new media era can get churned out there constantly,” said an obviously irritated Obama.

“I will always put my money on the American people, and I’m not going to be worried too much about what rumors are floating around there.”

The quip about the birth certificate being plastered to Obama’s forehead has already prompted some comic images to be posted online, incliding this one at Sad Hill News:

A Pew poll this month revealed an astonishing 18 percent of Americans identify Obama as Muslim, and only a third identified Obama as Christian.

Another poll by CNN, whose editorial commentary largely supports President Obama and his policies, delivered some bad news on his apparent birthday earlier this month: 6 of 10 people are uncertain the president was even born in the United States.
