We need to take a middle road, finding out how sincere and capable Trump is. And letting him know that yes, We The People intend to hold his feet to the fire.
I do agree that we need to hold any candidate’s feet to the fire.
And, since there is law already on the books that enables the building of about a 1000 miles of fence/wall and implement other security aspects of immigration control, then Trump would be without excuse for not doing so.
But, he’s the only one saying that he’ll do what is necessary.
