There is a broad spectrum of viewpoints on the Right from centrist all the way to ultra Right, with many points in between. This is why we struggle to reach consensus on many issues. In contrast, the Left finds it easy to reach consensus because they are almost uniformly way far Left. Their spectrum of viewpoints is far more narrow.
We on the Right somehow need to work together for the common good. And yes, that means learning to compromise to get Reagan's 80% and live to fight another day for the remaining 20%.
That is one of Reagan's worst statements ever and it is used by conservatives to justify being a traitor to the Republic.
