There was no "sorry" or "my bad" or "apologies for dragging your name and our nation through the mud by encouraging unhinged birther conspiracy theories."
Instead, Donald Trump declared "I'm very proud of myself, because I've accomplished something that no one else has been able to accomplish"-and, just in case anybody missed the self-congratulation, " I really did a great job." This is the political equivalent of lighting a house on fire, calling 911 and then expecting a medal.
Which is almost an apt analogy. A more tailored analogy would be "...the political equivalent of double parking your car in front of the fire hydrant, moving it, and then expecting a medal." But I digress...
Donald Trump is really just a minor figure in the birther comedy, a person who grabbed a spotlight at precisely the right moment to get caught in the glare. His celebrity, to be sure, forced the question to the surface, but had it not been for the real asshats in this farce, the Orly Taitzes and John Corsis of the world, Trump would have been politely escorted off the stage.
After all, there had to be a base of support for the ridiculous and regularly-debunked notion that somehow President Obama was not American nor qualified to be President.
Which is why you need to read the rest of that article I linked to.
