They went that-a-way.

Having vanquished each and every one of his Republican foes, presumptive Republican presidential nominee and America's least successful casino owner Donald Trump must now, time permitting, pivot to the general election. To see how that's going, we check in with his New Hampshire offices.

In the middle of a workday this week, Trump’s state headquarters was locked, windows covered in paper, and displayed a note for visitors to call a phone number for access. By the door, there were about a half-dozen large blank posters, with this message clothes-pinned to the boards: “For the Donald Trump campaign. He’s embarrassing, but he’s ours.”

It does seem Donald Trump leaves more than his share of shuttered buildings in his wake. Also, I don't know that I'd trust the (eventual) staff with blank posters—they may decide “He’s embarrassing, but he’s ours!” to be as good a campaign slogan as any.

Asked about the state of Trump’s campaign in New Hampshire, Steve Stepanek, Trump’s state cochairman, pointed out that about 10 percent of the entire Trump national staff has New Hampshire roots, including the campaign manager, Corey Lewandowski, and the newly installed national political director, Jim Murphy.

Hey now, you're forgetting the next most famous New Hampshire Trumpite, Veterans for Trump co-chair Jerry DeLemus, who was recently arrested and charged with nine federal offenses for his role in the Bundy Ranch standoff.

Oh … perhaps that's why Trump's New Hampshire offices are empty, with nobody answering the phones or returning reporter calls? Maybe the people with the keys to the place are all in jail on firearms charges?
