Here's an excerpt from the Donald Trump speech in Springfield, MO, via RealClearPolitics.

But to me, it's the Democrat Party, and they aren't just extreme. They are, frankly, dangerous, and they are crazy. They're crazy.

Democrats want to abolish us. In other words, they want to abolish immigration enforcement entirely, let violent sadistic gangs, like MS-13—the worst gang in the world—run wild in our communities.

I've seen our guys from ICE. I've seen it, I've watched it. MS-13, they're tough, but they're not tough like our guys. They're not tough like our ICE people. Our guys and girls, they go in there—man, I'll tell you, it's unbelievable. And that's what we need. You know, you can't have, like, Oh, isn't he a wonderful person. He's nice. He's—we need tough people.

These are tough people. These are sadistic, mean, sick criminals. ICE is incredible, and we're going to protect them, and we're going to cherish them, and we're going to thank them very much for keeping our communities safe.

Democrats want to open borders, which equals massive crime. Republicans want strong borders, and we want no crime. We don't want crime. Democrats support sanctuary cities, cities of crime.

They'll flood our streets with criminal aliens and violent gangs. Republicans believe that our country should be a sanctuary for law-abiding Americans, not criminal aliens. Democrats want to dismantle law enforcement and attack the heroes who keep us safe. Republicans stand proudly with the brave men and women of ICE, border patrol, and law enforcement.

Everyday, our heroic ICE officers are tracking down gang members, predators, thieves and killers. And we are either throwing them the hell in jail or throwing them the hell out of our country.

So never made a lot of sense to me, somebody who wants to open borders—crime, and somebody wants higher taxes. Think of it. So you got open borders, you have crime. Here's their platform, crime and high taxes. I don't like that. I don't think I could win. That's not a good platform. (Emphases added.)
