If "out there" includes only TBR, you're missing a significant percent of RDS supporters who feel this way. You're right they don't say "I won't vote for anyone but DeSantis" ---- they come from the other corner with the assurance they will never vote for Trump.
Thank you for admitting the two are not the same. Personally, I will vote for anyone Conservative. If Trump chooses to be a Conservative, then he gets my vote. Could care less about his cult status.
Of course I don't see that happening, primarily because of the lies I get bombarded with from his most loyal cultists. At least in 2016, there were one or two who gave me bogus narratives about how Trump was going to get rid of baseline budgeting. They at least could talk the talk. But today, I get nothing but contempt and false claims and accusations from that side. If you want my vote, that is going to have to change. But then you know that already. Yet all I get is a continuation of the latter.
If by some miracle of God, Donald Trump showed some humility, that would go a long way towards his goal of regaining the Presidency. But instead, he just keeps going further and further to the Democrat side.
