From a 1st Amendment point of view, this case was pretty much a slam dunk. If MO elects to allow groups to volunteer to clean up stretches of its highway rights-of-way, it can't deny participation to particular groups based on belief, even groups whose views the state finds abhorrent. Of course, no state has to have an adopt-a-highway program, and some states have cancelled theirs for this very reason.
A lawyer friend who has followed this case for some time said to me that MO should let the KKK volunteer, figuring they won't last long in the face of the "abuse" that is sure to follow.
