He has said that he wants all the illegals to be deported and that some "good ones" would be allowed back in if they go thru the legal process. Have you read Trump's position paper on immigration? It is the best one ever presented by a Presidential candidate.
Cruz and Rubio support legalization of the lawbreakers allowing them to stay and work here, i.e., amnesty. They don't have to leave and apply outside the country to reenter.
How does Trump propose to physically deport ALL those millions who have entered illegally? Is that realistic or is it just rhetoric? And then to let the “good ones” back in—a path to citizenship—to me that sounds like a form of amnesty.
Rubio does support legalization but Cruz does not.
