@dcdeejay well they don't have to bridge that divide, and the general principle is that courts should not be bridging divides that aren't in front of them.
The question today isn't even whether Trump can or can't remain on the ballot. The appeal is to consider whether the CO court made an error in it's own judgment about ballot access.
That's it!
They aren't even supposed to be re-litigating the lower court's finding, but just reviewing the process to make sure it was followed correctly as per state law.
So eligibility to serve is a question even farther out of their present jurisdiction to tackle.
