Shux, I disagree, when a state court disregards the US Consitution, which is what the FSC did(changing the rules after the fact), it is very much a federal case. I guess you were watching CNN? MSNBC and FoxNews said it was very likely that the USSC would grant a stay either be it by Kennedy alone or by all of them deciding on the issue.
I can see them throwing out the ballots in spite of them saying every vote should count. Overturning three findings of facts though, is highly weird and unheard of.
