Not ALL of both parties. I believe the majority of republican office holders and republican voters want the borders controlled. We do have some powerful open borders republicans to deal with but the dems are like 98 percent
You are correct about the voters, however, there are only about 50 in the House and a handful in the Senate that side with the citizens and the rule of law.
Most of the elected GOP are indeed on board the Cheap Labor Express and need to be replaced.
