Only one candidate says he would enforce existing immigration laws, Trump. Not Cruz, not Paul, not Carson, not Carly, not Rubio, not Bush, only Trump says he will enforce existing laws.
I agree, he’s the best on it—but even Trump wouldn’t enforce existing laws.
If he did, those illegals whom he sent home on his touch-back system largely wouldn’t be eligible to re-enter the US, let alone do so with legal residency.
