We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
I am not sure how new it is, though. The masses of voters were never strongly ideological, just the pundits. Donald Trump is post-ideolological, which is why he could win an election.
Barry Goldwater and Rand Paul were ideological. Well, Reagan was too, in some ways, but he was more American Flag primarily. Like The Donald is. How much did Reagan do to advance the Conservative agenda? Not too much. He was handcuffed. I wish he could have accomplished more such as eliminating entire federal departments.
I don't know if it is the end of Left and Right but certainly the appeal of a unique American identity and sovereignty supercedes ideology, for now. Whether it will prevail or not remains to be seen. Yet it is heartening that at least among men it still does.
