People with half or more of a brain are leaving the Republican party.
Here's a good example from Texas...

A Texas judge puts the blame squarely on Tea Party Republican rhetoric
for his decision to run for re-election as a Democrat in a campaign
video he released on Sunday.

“Rational Republican beliefs have given way to ideological character
assassination,” Bexar County Judge Carlo Key says in the video, over
shots of Sen. Ted Cruz (R-TX) and other Republican lawmakers.
“Pragmatism and principle have been overtaken by pettiness and
bigotry. Make no mistake, I have not left the Republican party. It
left me.”
