Unfortunately and sadly, Trump-XYZ Party will replace GOP! But it will be short lived! One can only prosper so far purely on divisive tactics.
Today’s GOP, as you are summarizing, has no conservative ideology left:
1. No efficient market (no trade protectionism to tariffs)
2. No deficit to now all deficit
3. Free and fair election- No more if they have their ways
4. Freedom of speech- no more unless you agree with Trump.
5. Democratic Republic to Autocratic Kingdom
6. Pro-life only when it comes to unborn babies
7. Individual responsibility, moral character and integrity to rampant corruption at every level
8. US the world leader to US the world loner
....
anyway only time will tell!
