The Democrats have won the latest round in the battle over Colorado’s congressional re-districting.

A federal court has thrown out the last remaining challenge to Colorado’s congressional redistricting plan, saying the state Supreme Court resolved the case when it upheld a plan backed by Democrats….The ruling, handed down Wednesday and made available Thursday, is a setback for the GOP, which has been seeking to overturn the state’s congressional district map for two years.

Is this the end of it? Hardly. Republicans say they will appeal the ruling to the Supreme Court.

An appeal would go directly to the U.S. Supreme Court, instead of an appeals court, because the original case was handled by a three district judges and not the customary single judge. Federal law requires redistricting lawsuits to be handled that way.
