Who does President Obama think he is: Donald Trump? At a Democratic fundraiser in Las Vegas he called opponents of his agenda "crazies." His White House flacks had to walk back the slur, saying Obama might have been "a little flip" with his rhetoric.

Last year Jeb Bush said he would run for president only if he could "do it joyfully", observes blogger Keith Koffler. "But then along came Donald Trump and his crazy-high poll numbers," he adds. But as Bush lagged in the polls, he plodded along, calling himself a "joyful tortoise." As Trump's attacks on him get harder, Jeb is acting more like a "snapping turtle."
