re: What exactly is a RINO?

Anytime this subject comes up, I’ve come to ask what lasting/notable Republican/conservative achievements did the GOP gain for America and Americans in the 2 to 3 decades prior to Trump coming down the escalator?

20 to 30 years is not a small sample size so there should be some things easily pointed to/reminded as good examples.

If there are such examples then why did the GOP fail so badly in communicating those Republican/conservative achievements to the public?

I think ultimately the GOP has only itself to thank. If a significant chunk of the GOP base had been happy with the country’s progress under leaders like Bush, McCain, Romney, etc. then Trump/populism probably wouldn’t have been able to gain the foothold it did.

ETA - And my viewpoint on this always earns a few downvotes but to date, no one can ever tell me why my viewpoint is incorrect.
