The impression I got is that the ruling says just one state should not have the power to determine the outcome of a national election. Practically speaking it may make sense, but it's not what the constitution says. At least how the Colorado courts and I would read it. I imagine one could ask, how many states does it take. How does the 14th amendment actually work in national elections that would prevent insurrectionists from taking office. Leaving this up to the senate is sort of like the fox in charge of the hen house. Disappointing, but not a surprise.
If I get the news right, the next big legal challenge for Trump is the presidential immunity case. It looks like Trump is using his typical delay tactics and denying the public of a speedy trial.
