Donald Trump is beginning to look presidential.

The billionaire real-estate mogul, part-time reality TV star, and the guy who has never had a good-hair day stepped before a throng of reporters on Wednesday and took credit for finally getting to the bottom of the Obama birth-certificate riddle. Trump said, if not for his investigators in Hawaii who were digging toward China in search of the truth, the president would not have come out with the “long-form” birth certificate — the one the so-called birthers have been swearing doesn’t exist since Jan. 20, 2009, while making the claim that Obama, since he isn’t a native, is forbidden by the Constitution from calling 1600 Pennsylvania Ave., Washington, D.C., home.

So Trump, while being proven wrong, claims victory, which certainly makes his impending foray into politics more credible. But he might have to share the credit in finally flushing out the truth.

Mr. Trump, allow us to introduce you to Jerome Corsi, the author of “Where’s the Birth Certificate?: The Case that Barack Obama Is Not Eligible to be President,” which sits atop Amazon’s best-seller list, a feat made less amazing since a fat one-third of Americans bought the myth that Obama wasn’t born in Hawaii, but made more amazing since the book doesn’t publish until May 17.

We now know that our president was born at 7:24 p.m. on Aug. 4, 1961, at Kapiolani Maternity and Gynecological Hospital in Honolulu. The certificate identifies his mother as Ann Dunham Obama, an 18-year-old white U.S. citizen born in Wichita, Kan., and dad as a 25-year-old black citizen of Kenya named Barack Hussein Obama.

Obama’s birth place has for too long been a dumb distraction, but the time will be soon that the debate should be buried. We accept that there will be challenges to the document’s authenticity that will string out this ridiculousness a wee bit further, but when there is no longer any doubt, can everyone sign a pledge to move on?

In fairness to the birthers, their frenzy was whipped up — perhaps purposely — by Obama, who could have done at any time what he finally did this week, which was petition the state of Hawaii to release the long form. Instead, Obama kept feeding the line, and there was no shortage of takers, as the noise only got louder and louder until the oxygen was sucked from the room this week.

If we assume that Trump and Corsi were not the catalyst, why now Mr. President? Could it be that Obama needed his own distraction, a reason for Americans to glance away from three wars, a multi-trillion-dollar deficit, $4-a-gallon gasoline, an economy that just can’t get traction, and a Congress more interested in partisanship than in solutions?

If so, the president probably succeeded. But soon enough, the conversation should be steered toward things that matter to the American public, and away from where Obama was born.

At last.
