Trump has an opportunity here to earn some respect for people like Me who don't support him.
If he is as good at the deal as he claims he would do this.
Hold a meeting with the Democrat Senators and make one more single offer. A take it or leave it kind of offer.
We will take up DACA as you want AFTER the spending bill is passed. If you continue to withhold support for this spending, I will take DACA off the table for the remainder of the time I have in office. We will win the court case and I will rescind DACA and begin deporting the dreamers. If a bill for DACA makes it to my desk, I will veto it. You can take your chances that I'll lose in 2020, or you can try again in 2024 when I'm gone. Of course, by 2020, I will have deported all 800,000 of the dreamers.
Your choice.
