Well reasoned argument, but I do have one quibble with your salient point:
If we are to demand that our candidates “DO” something, Trump is in trouble. Why? Because the things that Trump has done are the antithesis of what we want for a President. He’s spoken about a need for more gun regulation, he’s used eminent domain improperly, he’s supported the Clintons, he’s used H1B visas to bring in foreign workers. The thing we like about Trump is his laser like focus on immigration. However, that is just talk right now.
So, if our demand is for candidates to DO something, I do not believe that any will meet our criteria.
His immigration plan would be precisely what I want in a president.
What he would do on the positive side would far outweigh anything negative. But standing still, which is what virtually everyone else offers, is just not an option. Nation won't be here in four more years.
