Let's be honest: Republican politicians don't give one solitary shit about immigration. If they did, they would have voted to pass the Senate bill that they themselves negotiated in which Democrats gave them everything they said would address the so-called "crisis". But they voted against it, either because they know there isn't really a problem (which in fact, there isn't), or because they don't really want to solve it (which, in fact, they don't).
So when you hear them appealing to white supremacy and xenophobia by whipping up fear of an imaginary "invasion" of Spanish-speaking people with brown skin, remember they refused to do anything about it when they had the opportunity to do so. They didn't even bother to hide that that's what they were doing—they have that much contempt for their own voters. Don't accept the premise of their fearmongering.
@SteveCarll67 the cult members can't do anything but what dear leader tells them. My hope is the R's numbers have decreased and they won't vote for him or just stay home.
