Depends on the Republican.
Mitt Romney and John McCain were "nice" back in '08 and '12.
If JD Vance is the candidate for POTUS, and he likely is at this point, he won’t hold back when it comes to exposing the hypocrisy and perfidy of Newsom - and how he has utterly destroyed the Golden State.
Fortunately, we’ve entered a new era and Romney and McCain are looked at as the fools and appeasers they are and were.
Let the lefty media scream, yell and stamp their little feet - they too have lost all credibility.
