The current Republican nominee ran his entire campaign on hating immigrants and has been known to hire illegal immigrants. They don't actually want to crackdown on it they just want to campaign on it.
Legislation is meaningless if it is not going to be enforced or if it will be used to destroy competition. As in law enforcement cannot deal with all cases, but they certainly can be nudged to deal with businesses that corrupt government doesn't want operating.
I don't know that they will. For example, 90% of Trump's previous platform was the wall. That's all he could talk about. No wall to be found, and he doesn't even mention it anymore. Things change from campaign to office.
