For me, it depends on who is nominated. I won’t vote for any Republican that betrayed Trump. Not even if there was an exact tie and my vote meant the difference. I’m not saying they have to be Trump or Reagan reborn but my line in the sand is no traitors.
It seems to be the ELECTED 'Republicans' that are trying to stuff Trump under the bus.
I have heard of no large scale abandonment of him by the grassroots folks who VOTED for him.
