The peoblem is to many whites now support amnesty and are willing to sell the country down the river. Trump is willing to give amnesty in return fo his wall. He doesnt realize amnesty will ensure a permanent Democrat majority, with or without his wall.
America is dead
By the time the negotiations are done, the "wall" will come down to no more than some additional stretches of border fence.
Worse still, allowing the "Dreamer" anchor babies to stay sets the same precedent that all previous amnesties to illegals set. The loud and clear message to invaders is "come one, come all, and if you and your kids just squat here long enough, we'll make you legal." It's like ringing a taco truck dinner bell.
And the wall will be meaningless after we have 4 new blue states with significant EVs.
2020 election will be a snoozefest.
