Watching a recent White House press conference video at Politico, I am more convinced than ever that the White House is having fun and games with the Birth Certificate Truthers.
(FWIW, I have tried to take their arguments seriously, but the whole thing seems designed to be immune to serious debate; I think that even if Barack Obama produced the “long form” copy they demand, it too would be labeled a forgery.)
Here’s the press conference video:

From the dialogue between Press Spokesman Robert Gibbs and WorldNetDaily’s Lester Kinsolving:

…Gibbs appeared incredulous. “You’re looking for the president’s birth certificate? It’s on the Internet, Lester.”
“Long-form, listing his hospital and physician,” Kinsolving clarified.
Laughing, Gibbs replied: “Lester, this question, in many ways, continues to astound me. The state of Hawaii provided a copy with the seal of the president’s birth.
“I know there are, apparently, at least 400,000 people who continue to doubt the existence of and the certification by the state of Hawaii, of the president’s birth there,” he continued. “But it’s on the Internet because we put it on the Internet for each of those 400,000 to download. I certainly hope by the fourth year of our administration that we’ll have dealt with this burgeoning birth controversy.”

Actually, it looked more to me as if Gibbs was having fun than being astounded.
I think they want this to be an ongoing, burgeoning — and above all funny — controversy for four years.
It beats having a serious debate over whether the country should head in the direction of socialism. Leftists want nothing more than to be able to paint their enemies as crackpots, and the more Birth Certficate Truthers there are, the easier that task becomes.
Besides, the Truthers are funny, while socialism is dreary, and everybody wants a good laugh.
I’m wondering why Bush didn’t try this with the 911 Truthers.
