Have you even observed the influx of Democratic voters in the past decade?
Absolutely it is a huge problem that needs attention. But all is not lost at this point. Cruz vs O’Rourke is a special circumstances. It was a midterm when the president’s party loses seats. In the house, Paul Ryan was a disaster for Republicans.
Trump is taking action with the ICE raids and border security. One missing piece is governors actually doing anything about illegal voting.
