The issues Donald Trump has championed should be the top GOPe priorities, but party elites (idiots) are obsessed with diversity and winning the Hispanic vote (and not alienating Muslims, I guess).
In any case, at the New York Times, "Inside the Republican Party’s Desperate Mission to Stop Donald Trump":
Despite all the forces arrayed against Mr. Trump, the interviews show, the party has been gripped by a nearly incapacitating leadership vacuum and a paralytic sense of indecision and despair, as he has won smashing victories in South Carolina and Nevada. Donors have dreaded the consequences of clashing with Mr. Trump directly. Elected officials have balked at attacking him out of concern that they might unintentionally fuel his populist revolt. And Republicans have lacked someone from outside the presidential race who could help set the terms of debate from afar.Via Memeorandum.
The endorsement by Mr. Christie, a not unblemished but still highly regarded figure within the party’s elite — he is a former chairman of the Republican Governors Association — landed Friday with crippling force. It was by far the most important defection to Mr. Trump’s insurgency: Mr. Christie may give cover to other Republicans tempted to join Mr. Trump rather than trying to beat him. Not just the Stop Trump forces seemed in peril, but also the traditional party establishment itself.
Should Mr. Trump clinch the presidential nomination, it would represent a rout of historic proportions for the institutional Republican Party, and could set off an internal rift unseen in either party for a half-century, since white Southerners abandoned the Democratic Party en masse during the civil rights movement.
Former Gov. Michael O. Leavitt of Utah, a top adviser to Mr. Romney’s 2012 presidential campaign, said the party was unable to come up with a united front to quash Mr. Trump’s campaign.
“There is no mechanism,” Mr. Leavitt said. “There is no smoke-filled room. If there is, I’ve never seen it, nor do I know anyone who has. This is going to play out in the way that it will.”
