I deal with this group of elderly elephants on a local level. They are stuck in the 50's where politics was polite conversation, the GOP was a glamorous group of people sipping cocktails and looking down their noses at everyone.
My apologies to my elders here who have adapted and now actively fight the good fight, I don't want to group you with the country-club set.
I think your comment might make the most sense of any. I’ve tried and tried to understand RINO thinking, and this simple explanation might make the most sense. They are from the day when politics was a polite debate tournament, not a down & dirty fight for our lives and liberty.
