GEORGE STEPHANOPOULOS (HOST): Meantime, the number of prominent people comparing you to Adolf Hitler is actually growing by the day. You saw over the weekend, Louis C.K. Also Glenn Beck, he did that on This Week. And he called you “a dangerous man.” And yesterday the Mexican president said you're using the same kind of language that ushered in Hitler and Mussolini. I can't remember that kind of comparison being used against any other presidential candidate. Does it suggest to you, you should tone down your rhetoric and your tactics?

DONALD TRUMP: Well maybe so, but I mean I -- look, I have a tremendous following. We want to make America great again. It's a strong following. I don't know about the Hitler comparison. I hadn't heard that, but it's a terrible comparison. I'm not happy about that certainly. I don't want that comparison, but we have to be strong and we have to be vigilant and people agree with that. And we don't want to lose our jobs to China and we don't want to lose our jobs to Mexico and Japan and all of these countries that are taking our jobs away from us like we're, like we're children. We don't know what we're doing. We have leaders that don't know what they're doing. We're losing so much in this country and we're losing the spirit and we just can't do it. So I have to be strong and, again, I have a group of -- I have a tremendous following. You know, the Republican -- the biggest story in politics is how many people are going to the primaries on the Republican side. It's a record number. They're up 55, 60 percent. Some are up as much as 100 percent. And that hasn't happened ever. They say it's never happened. And the Democrats are down 35 percent so something very positive is happening.
