As long as Trump is perceived as putting America First, he will continue to have huge support, even if congress stonewalls.
This is why Trump has the support he does, he is the only person who seems at his core to put America first.... period. Whether you agree with him or not, no one can seriously argue he is the only guy on either side of the aisle that is consistent in present what he wants as being America first, period.
Trump is a big government crony. He even stole his slogan from Reagan, whom he detested.
