I’m less amazed that they do this (it’s who they are, it’s what they do) than that the media lets them get away with it.

It’s hard to say which is worse: that so many prominent Democrats believe they aren’t responsible for any of Washington’s gridlock—or that they’d say these things anyway. Not all that long ago, a presidential spokesman using this language would be talking about murderers who hijacked airplanes or drove explosive-laden trucks into the barracks of U.S. Marines—not political opponents with differing notions about federal spending.

With suicide bombs going off daily around the world and funerals for the Washington Navy Yard victims still taking place, one might expect a modicum of rhetorical restraint from inside the White House. No such luck. For five years now, such metaphors have been the cudgel of choice for administration officials, along with their fellow Democrats on Capitol Hill and journalistic fellow travelers.

It all starts with President Obama, who routinely accuses Republicans trying to thwart his spending plans by putting “party ahead of country.” Last January, when talking—as Dan Pfeiffer was this week—about GOP insistence on trading spending cuts for agreeing to raise the nation’s debt limit—the president said he wouldn’t negotiate with those holding “a gun at the head of the American people.”

Joe Biden asserts Republicans are holding the country “hostage” with their spending stance, and in a 2011 meeting with congressional Democrats the vice president agreed with the suggestion that Tea Party groups were “terrorists.”

Among Democrats on Capitol Hill, it starts at the top, too.

On This Week this morning, they were shameless about saying that the lying president of Iran was “more reasonable” than Republicans. But I guess that’s who they are and what they do, too. At least Jake Tapper called them on it.
