Dude, take a look at trump’s poll numbers for registered republicans. You are the one who is not welcome in the modern GOP, and you should stop kidding yourself about that fact.
Why is Phill Scott then Governor of Vermont then? Not everyone in the GOP is a Trump-Lover, just like how not everyone in the Democratic Party is a Communist.
Vermont is almost entirely a blue state! Phill Scott is successful as a Republican in Vermont because he is able to win over democrats with a combination of moderate politics and a strong level of local credibility.
He would be destroyed in Texas or Florida. You’ve got to realize that the people that vote in Phill Scott every election are the same people that have consistently kept Bernie Sanders in power… a self professed socialist
