A couple of weeks ago, Jeb Bush, a GOP 2016 front-runner, gave America a brief tutorial on why he should never be president, spouting off a series of outmoded, fact-free responses. But it was actually a model tutorial on why no GOP contender should be president, as follow-up events underscored. It began with Bush telling Fox’s Megyn Kelly that he’d still invade Iraq, even “knowing what we do now,” to which Laura Ingraham replied, “There has to be something wrong with you.” Bush then fumbled Sean Hannity’s attempt to help clean up the mess, saying “I interpreted the question wrong, I guess,” then admitting, “I don’t know what that decision would have been.”

It might be a deep pool of GOP candidates, but are they ever swimming in the shallow end
