Actually, the rank and file are rallying, not splintering. This is a statement based in fear, and then again it is from the Clinton Cable Network.
Yup, this is just more concern trolling by the media about the fate of the GOP as they used to know it, a compliant tool of Leftists by posing as a fake opponent or alternative to the democratic socialist party.
The media and the Left are very concerned the pretense is vanishing. The media always has helpful advice for the GOP such as how to be more 'inclusive', more critical of white privilege, express more shame of the racial make up of the GOP base.
