No, that should be written, "...endorsing the lower court's decision..."
It's really tough to believe that 7 of 9 SCOTUS members were appointed by Republicans.
This denial by the USSC was an emergency appeal on the denial of stay, not the case in chief that Moore is appealling.
If I remember the time sequence correctly, just before and then just after the 11th circuit decision came down, Moore was asked by Judge Thompson if he wanted a stay. Moore declined to ask for one. Last Friday, the day before the rally, Moore changed his mind on the stay and asked the district court for an extraordinary stay, because the time period to ask for a stay had expired. Moore then appealled to the 11th circuit--twice--and they denied the extraordinary stay (I'm not sure if this was done Saturday or Sunday). That's when Moore made an emergency appeal to the USSC and they denied the request for an extraordinary appeal.
It was baffling then and it's baffling now why Moore refused to ask for a stay when he had the opportunity rather than go through all the emergency appeals.
