I bet Trump would compromise anything to close the deal. The “one issue” Trump supporters will not get what they want from a President Trump, because that one issue will be used as a battering ram against Trump’s weakness for having to make a deal.
Making the deal drives him. The Democrats will run roughshod over him by threatening to not budge on the immigration issue. By holding it hostage, they will extort all kinds of compromise from Trump. This is not real estate where there are other buyers if this deal falls thru that can be used as leverage against each other. He will only have one deal partner choice: Congress.
The Democrats refused to submit a full budget for like 11 years, maybe more. I lost track of how long. Suffice it to say they have held out on things long enough to outlast a President’s term limit.
You think Trump could sit there for eight years, not close a deal on something he wanted and leave office empty handed on that issue?
What makes you think Trump would ever try to pass an immigration bill the Democrats don’t like?
He would just let the next Repubicrat get in office and conduct business as usual. Trump wouldn't waste his time.
Trump's ego will not let him fail.
