We've always been stuck with two parties. So, we're only as healthy as the two parties, together. I used to see the Republicans as "practical" and Democrats as "experimental." There's a whole lot more to it than that, but, just in general, those are respectable terms and categories.
Republicans used to have the most of what would be considered "intellectuals" firmly in their favor. They might be considered TOO intellectual by younger generations. They prided themselves on their restraint and taking very calculated risks, and being mindful of the growth of government. There was open consideration regarding scientific advancements and how that would best be used in political/governmental practice.
50 years later? It's just a race to see how many still refuse to believe in Evolution, and how to best appeal to the ever-shrinking demographic of people who can only live with their mythologies in control.
And, Democrats are now even more unrestrained. Not to mention, their own fringe members kicking and screaming. But, you rarely see them telling scientists that "God will show us the way!" When only ONE SIDE will consider the methods of science, we're all fvcked!
The whole time, the oligarchs just clean-up! That was probably their plan when they bought the country. Follow the fear, exploit it, cash the checks.
