It's hard to see locally, but we're a country that's deeply divided on some core issues. Half the country wants gay marriage, the other half doesn't. A single-payer-advocating socialist almost won the Democratic primary, where his opponent is talking seriously about trying to "roll back" the ACA ("Obamacare"), this president's legacy domestic policy achievement.
I feel like half the country wants to become more like Europe -- more socialist, higher minimum wage, high taxes, big social safety net, free universities, lots of job protections (and the reluctance to hire that goes with it), minimal/no religion, less marriage, whereas the other half wants to step back about 50 years to picket fences, nuclear families, and a more isolated national existence.
We aren't going to have another civil war but I wouldn't be surprised if, looking back, we're more ideologically divided now than the country was, then.
closer to 2/3 : 1/3 than half/half [0]
The same degree of division with different geographic and class distribution could very well not have similar results.
we definitely need term limits.
