NRO's Goldberg: “Why Did The WH Take Such Sweet Time Releasing” Obama's Birth Certificate?

In an April 27 National Review Online blog post titled, “The New Burning Question,” Jonah Goldberg wrote:

I haven't studied the just released PDF of Obama's birth certificate. But assuming there's nothing in there about a birthmark that resembles the numbers “666” or about how his father worked for the KGB and -- of course -- assuming that the font in question matches typewriters of the time (Let's get Dan Rather on that): I figure this puts the birther thing to bed once and for all. Good.

But it does raise the perplexing question: If this was possible all along, why did the WH take such sweet time releasing it? Could it be that this White House, continuing a tactic used by Democrats for years, actually liked being able to cast their opponents -- often through guilt by association -- as paranoid nuts? No, that couldn't possibly be it.
