Hold it --

Before we get carried away, to be fair to Obama, I can't find a transcript of his remarks. Although the CBS story that Ace of Spades relies on characterizes Obama's remark as having claimed his uncle / grandfather / composite character was among the U.S. troops liberating Auschwitz, it's a paraphrase not a quote. That ought to be treated as a big flashing "caution" sign. The WaPo account that Allahpundit uses to bolster the claim also paraphrases, but indicates a less obviously flawed claim: that Obama said that his uncle was "one of the first U.S. troops into Auschwitz."

To be sure, he may well have stuck his foot in it again; nevertheless, opponents of Obama should be careful: be sure that we're attacking him for gaffes he has actually made before opening fire, otherwise we end up looking like the boy who cried wolf, and people stop paying attention. Measure twice, cut once, as they say.

Added: Newsbusters has the video (unfortunately Jodi Miller isn't in this one; you'll find her here). It turns out that both ABC's and the WaPo's paraphrases are correct: Obama said that his uncle "was part of the first American troops to go into Auschwitz and liberate the concentration camps." I'm minded to give Obama the benefit of the doubt in this instance. I think extemporaneous remarks should be given some latitude, absent good reasons not to. As long as it's verified that a relative that Obama has long considered an uncle (playing gotcha about whether Uncle Phil is actually your parent's sibling won't cut it if you've called him uncle Phil your whole life) was a member of one of the earliest groups of U.S. forces into Auschwitz (or any other concentration camp - as Tully points out in the comments, U.S. forces liberated the Buchenwald and Mauthausen-Gusen concentration camps), we'll chalk it up to Obama's inept public speaking. If even that claim turns out to be false, however, all bets are off. Wrong on the specifics in off-the-cuff remarks is forgivable (Scalia once gave a speech referring to a case called BMW v. Bush that he dissented in, making a point of saying that it wasn't the Bush you're thinking of; the case is actually BMW v. Gore, so you can see which wires got crossed), but the story has to be basically true for him to get out of this one.
