I predict this is going to be their next abortion issue. They'll promise an invasion of Mexico to get their base riled up but will do nothing. The blowback from invading a sovereign country in the midst of terminal, unmanaged socioeconomic decline could be fatal.
However the next generation of right wingers will believe it at face value and actually try to execute it, just like abortion.
