The Democrats are total fools if they don't fund the border wall. Trump has now said publicly that he will have the military build it if he can't get Congress to pass it.  What happens then? The Democrats lose the biggest bargain chip by far that they will have through his entire term.  Military builds the wall, then DACA becomes even more urgent for them.  They will need to make the best use of the illegals that are already here since the influx of new ones will be slowed to a trickle.  Now all of a sudden Trump is the one with the bargaining chips and the wall is done and off the table.  Now he can use DACA to get the REAL comprehensive immigration reform.
