Clinton said Trump's "negative, nasty form of politics" resonates with his supporters because they may not like migrants, and are homophobic, racist, and misogynistic.

"It's a classic tale of an authoritarian, populist who really has a grip on the emotional psychological needs and desires of a portion of the population," Clinton said of the Trump saga. "And the base of the Republican party, for whatever combination of reasons -- and it is emotional and psychological -- sees in him someone who speaks for them. And they are determined that they will continue to vote for him, attend his rallies, wear his merchandise, because for whatever reason, he and his very negative, nasty form of politics resonates with them."
