I just don't know how people that have seen the last four years of our politics can trust that Never Trump Republicans will remain so when the costs get both real and severe. We saw after January 6th- when everything was perfectly set up to finally take a stand against Trump - far too many Republicans cave during the impeachment.
That isn't even to mention that by putting the GOP in the majority, one would be also empowering GOP leadership beyond the individual candidate. GOP leadership that may be beholden to Trump.
We see how well that goes in the House for this GOP.
