It was D (for desperation) Day among the GOP establishment today.
There was the Mittster warning America that security and prosperity would fly out the window with a Trump nomination. Romney doesn't get the fact that, from the point of view of street-level folks, America's security and prosperity has already been squandered by the perpetual-war establishment types.
Then, to prove that they're just as clueless as Romney, seventy-some charter members of that establishment posted an open letter on the War On the Rocks website. Yup, a president who could get along with Putin and be neutral on the Israel - Palestine conflict would be bad news indeed. That this clique of war cheerleaders feels threatened by Trump tells me he must be doing something right. A "Dump Trump" plea signed by the likes of Daniel Blumenthal, Michael Chertoff, Eliot Cohen, Robert Kagan and a few dozen like-minded Washington insiders isn't going to make much of an impression on the millions of regular folks who have begun to realize that the trillions pissed away on unnecessary wars at the urging of these people has only made America poorer and less secure.
In fact, it's these war cheerleaders who have brought America down. Bill Kristol gave the game away when he revealed that the GOP elite would be better served by having Hillary in the White House. Unlike Trump, Hillary is a reliable advocate for senseless military interventions and endless weapon sales to all sides in virtually every conflict. What that should tell the Republican rank and file is that their party has long since been hijacked by the military-industrial complex.
It's no wonder the elite feels threatened by a candidate who is bringing democracy back to the party.
