The illegals will neither vote (legally) nor have citizenship by the next election so their vote will be NILL. And the next president can reverse the executive order decreed by Emperor Barack. The net result of all this will be to further DESTROY the Democrat party.
Do you really think there will be the political will to take back the work permits and SSNs from millions? The GOP will be left to developing legislation that will legitimize what was done. I am confident that the GOP Congress will pass immigration legislation that allows them to stay and work here. It is a fait acompli.
We had a 2012 Obama DACA Dreamer amnesty that legalized 580,000 to date. The Reps scarcely reacted to it agreeing in substance what was done. In fact, Cantor was readying the GOP version of the Dream Act. You can bet that these Dreamers will be put on a path to citizenship regardless of who is running Congress or the WH.
