I am not sure that Trump understands your expectations. I say that because Trump says the gate in the wall will be big, maybe yuge; Trump supports touchback immigration where all the “good ones” can come back - expedited he says - through the big gate; and Trump supports the Dream Act (unless he has flipped again; can't keep track).
Trump will walk away from his vow to build a wall faster than he walked away from his several marriage vows.
Maybe, but I do not think so. Trump did not vote for amnesty and he did not push for a 500% increase in H1B visas as other candidates have. Trump does not have to understand my expectations. The laws which govern legal immigration are set solely by Congress, not Trump or any other President. I can tell when somebody mentions “touchback amnesty” that they very likely have zero experience with the US immigration system. One thing you have to admit is that Trump is undeniably 100% NBC American which is more than can be said for others in the race.
