Donald Trump doesn't have a ground game. Does he need it to win?

Donald Trump says he can win big in November by turning blue states red.

“I will win states that no Republican would even run in,” he said, with his staff telling the Associated Press he is sending teams into 15 states by the end of May to begin that fight. But on the ground, there are few signs the action of building a large campaign apparatus is underway.

One Trump campaign source told NBC News that boasting to the AP of 15 state directors being deployed was a “piece ginned up to make it seem like we’re doing something when we’re not.”

“It’s either fluid or non-existent,” the source continued, speaking on the condition of anonymity. “I would lean towards the latter.”

Asked about his ground game on Thursday, Trump said the Republican National Committee would help substantially.
