At the National Prayer Breakfast this week President Obama twice mispronounced corps as corpse. While those on the left (including the media) no doubt will say that this display of the commander-in-chief’s ignorance about the Marine Corps is no big deal, they said something else entirely about Dan Quayle’s misspelling of potato. They said the vice president’s mistake, which is less egregious than Obama’s latest gaffe, had everything to do with his intelligence and fitness for office. So if they decide to give Obama a pass, they will have to send the former vice president an apology. That’s spelled A-P-O-L-O-G-Y.
