IT’S ACTUALLY MORE LIKE A LIMP-WRISTED SLAP: Jeb Bush Takes a Cue From Donald Trump’s Playbook: Punch Back.

Mr. Trump has called Mr. Bush’s immigration plans “baby stuff” and his education policy “pathetic.” He has expressed mock sympathy for Mr. Bush’s audiences, who he says must be so bored that “they’re sleeping.” . . .

After enduring those slings and arrows for weeks, to the mounting dismay of supporters, Mr. Bush, the former Florida governor, and his aides have decided to venture outside their comfort zone and borrow a page from Mr. Trump’s playbook: Hit back, with force and creativity, over and over again in the coming weeks.

It is a turning point in Mr. Bush’s campaign that was on display Monday in McAllen, Tex., along the border with Mexico. There, Mr. Bush called Mr. Trump’s immigration plan “unrealistic,” described his policies as un-Republican and acidly recommended that the businessman read Mr. Bush’s book “Immigration Wars” to acquaint himself with a practical solution.
