> the US is far more polarized and contentious than it ever was before.
This is completely divorced from reality. Everything that has happened in the past 10 years is a mere candle to the bonfire that was the Civil War. You must be discounting datapoints you didn't live through if you really believe what you've said here. Shit man, the present state of affairs is tame even compared to the 60s and 70s.
The decision to even hear the case is radical and affirming would represent a massive shift away from democracy in the US as we know it.
>Issue: Whether a state’s judicial branch may nullify the regulations governing the “Manner of holding Elections for Senators and Representatives ... prescribed ... by the Legislature thereof,” and replace them with regulations of the state courts’ own devising, based on vague state constitutional provisions purportedly vesting the state judiciary with power to prescribe whatever rules it deems appropriate to ensure a “fair” or “free” election.

If democracy died every time somebody got mad at the outcomes and made claims like that, it would have been dead before it even started, and subsequently re-died every year since. What exactly was so democractic about SCOTUS permitting the executive branch to write their own laws anyway? Writing laws is meant to be the job of Congress. You can claim Congress is insufficiently democratic due to gerrymandering, but less democratic than the judicial and executive branches? Give me a break. Congress remains the most democratic of the three, and this SCOTUS decision gives power back to Congress.
