Thanks!! That's about the best explanation I could ask for.
I could definitely see how the Republican Party's adoption of liberal economics abandoned a red toryism that was espoused by Hamilton, Clay, et al. And I imagine fusionism destroyed any vestige left of this old tradition, already rarer in the US due to the things you note. The stability idea is particularly interesting. Ealier in our history things like the Shay's Rebellion, the Whiskey Rebellion, and the Civil War might have made that different back then.
Also the frontier itself created a desire for stability, and with its elimination that also went away.
