You don't think his rhetoric against undocumented immigrants is racist?
Last time I checked "undocumented" immigrants aren't a race, and they also broke the law. It's not racist to attack people breaking the law.
It's pretty racist to attack a whole contingent of people and make broad negative generalizations about them and qualify with a half-hearted caveat that 'some' are good people. He's quite clearly drawing a line between "you" (the white audience he was speaking to) and the Other (i.e. the Mexicans) personified as rapists and drug dealers.
