The Morning Joe panel and Rick Tyler, former communications director for Republican presidential candidate Ted Cruz, discuss Republican presidential nominee Donald Trump’s ongoing divisive rhetoric, the weight of his words and who will “babysit” him through the rest of his campaign and into the presidency, should he win in November. Veteran columnist Mike Barnicle says: “For some people there was a very worrisome nugget in an NBC poll that 72 percent of registered Republicans still don’t believe (President) Barack Obama is a citizen of the United States.” And he asks of Tyler: “Does that trouble you at all in terms of the storyline of the legitimacy of this president and the legitimacy of past presidencies? That’s where Trump is going when he says it is a rigged election.” Hear Tyler’s answer and the rest of the conversation here.
