No doubt it will sail through congress since it represents the democrats' ultimate wet dream, an amnesty, which will end up being three or four times as big as we are told, plus getting Trump to do a Bush 41 backstab on his core supporters. Of course the usual republican sellout/cucks will support. They have wanted a big amnesty all along and no wall.
Trump supporters are wild with anger all over twitter. If this deal goes through and he doesn't build a lot of wall, he can count on not even getting the nomination for 2020. I'm not even sure at this point if building the wall will be enough. He is giving dems what Obama could not, a legislated amnesty. That cannot go unpunished.
