Is Republicanism a mental illness?

37. You shifted to "party success"

Party success is not the same as the size of "Republicanism".

I specifically mentioned Pew Research polls, not election polling. For example:
https://www.pewresearch.org/religion/fact-sheet/public-opinion-on-abortion/
Note that a very specific portion of self-identified Republicans oppose any access to abortion, while the majority of the public favors access to abortion. That portion is shrinking over time.

It would be interesting to compare public opinion over time with different parts of the Republican and Democratic platforms.

Those concrete results you gave are the result of many factors, and indicate we need to work on those factors, but they do not necessarily indicate "Republicanism" is on the rise. If the majority of the public agree with Democratic policies, but Republican candidates continue to be successful, then we are failing at message, turnout, voter enfranchisement, or other. If the majority of the public agree with Republican policies, then "Republicanism" will grow and, in my opinion, we're screwed
