“I just hope Republicans have the stomach and backbone to carry out this plan under intense political pressure, something I seriously doubt.”
**********
Your doubts are well founded. We’ve already seen that the Republicants have no stomach or backbone. Its a soulless party devoid of any convictions.
To paraphrase a quote often attributed to Patton: Trump would likely prefer to have the Democrats opposing him over the feckless Republicans “backing” him.
Q: Why would Republicans carry out a plan that their party opposes?
A: They wouldn't.
The GOP is the largest and best funded pro-open borders force in America today. Only the FR Imaginary GOP is against it.
