Why do you think they didn't appeal that decision? It made lots of sense for them to do so, because it would have cast the election in doubt and also have shown the spotlight on the eeevil Supreme Court, who gave the election to Bush, according to Rat dogma.
The reason they didn't appeal was if there was a protest in court on-going, the feds could have sent observers in under the guise of Civil Rights, as they did in Florida this last election (also in St. Louis).
Davis thinks he can win because of fraud.
