Some people imagine Obama was raised up in a leftwing, even Communist, home environment ~ (Grandma was a banker ~ so could be, eh ~ first ones in line for their Obama money as I recall), and the point there is that chilluns' raised around people like that soak up that ideology and can never get beyond it.
Some do manage to struggle out of the Red Diaper Baby stage, and there are books about it ~ David Horowitz wrote one, but are there books from RINO raised chillun who talk about walking it back into a society of real Americans?
I doubt it ~ the RINO condition seems to be one of those things that once you've tried it, you don't go back.
The fact that RINOism can't be escaped should concern us all, but it should also spur action to make sure that as we rid ourselves of RINOs we keep their heirs out of the Republican party as well.
They can, of course, continue to make donations, and that should satisfy them.
Counterexample: Hildebeast, who grew up RiNO in Chicago, was a Nixon Girl in '68, then got glommed on to by lefty LUGS at Wellesley and wound up in the SDS and married to Slick.
Other examples will no doubt occur to other readers deeply steeped in political history. Starting with Jim Jeffords and Lincoln Chaffee.
