Trump said Democrats won the Latino vote in the last election because they appeared more welcoming.

"The Democrats didn't have a policy for dealing with illegal immigrants, but what they did have going for them is they weren't mean-spirited about it," Trump said. "They didn't know what the policy was, but what they were is they were kind."
