Liberals hated it for it means people can move into exurbs on the state's Eastern side. Bad news for the People's Republics of Eugene, Salem and Portland.

"well meaning?" I dunno about you, but government planners I've seen are as far from well meaning as it is possible to get without moving to Mars. They are advocates of special interest groups whether it be Walmart or some bunch of ecofreaks. Whoever slips them the most generally gets the nod.
Not to worry. The courts will figure out what the people really wanted.
