No, the heart and soul of Republicans from Day One until today has always been rural, small town & suburban, small business, traditional Christian, patriotic, pro-military & law enforcement, conservative, small government.
And people like that are pretty much the same, North, East, West and South.
Sure, some of us have been pretty well educated, but Democrats have always claimed the highest posts in academia.
For a historical example, think of Democrat President Woodrow Wilson, former President of Princeton University!
So John S Mosby's claim that Northern Republicans don't "get" the South is absurd because in most ways we're the same kind of people, and decidedly different from your typical Democrats.
Of course, ex-Dixiecrats who'd like to be Republicans without having to give up their pro-Confederate Lost Causer mythology... sorry, not so much we can do for you folks.
That's true. Trump voters North and South, East and West aren't so very different from each other.
There is a split between the "elite" and the "populist" factions of the GOP, but I have to laugh when people are running down the senior senator from South Carolina every day and then start talking about some Northeastern elite within the party.
The Rockefellers, Roosevelts, and the rest are gone. Those who are left are voting Democrat. The average Northeastern Republican has more in common (originswise) with Giuliani or Christie than with the Rockefellers or Bushes.
Meanwhile, country club Republicans are everywhere. If Southerners can't stop electing them to the Senate, it's not the fault of folks up north. As time goes on, you'll see more RINOs -- and even Democrats -- elected in the South. And you'll hear the same voices blaming them on the Yankees.
