Let them in, but make them all go to California or New Mexico - states the GOP will never carry anyway (for President). Let those states go bankrupt. We get best of both worlds.
(tongue in cheek of course, but as long as they don’t turn red states blue, the damage is mitigated.)
This is part of the theory I posted and some got upset as if I were pushing it as a thing to do. The GOP will deal on immigration and move Marco Rubio to the front and go after it.
They are running scared to preserve the PARTY of the GOP
