I would normally argue that public referendums and placing controversial issues on the ballot are the best way to go to resolve zoning issues. But if the voters are a bunch of clueless "eighty-five percenters" that won't help at all. (These same "Billy-Bobs," after all, are the ones that vote for the Wal-Marts and Home Depots to come to town so they can save 50 cents on drywall).
If public opinion is swayed that easily, then its too bad that these individuals have the right to vote at all. Seems like the only thing you can do is give them tickets to a Shania Twain concert on election day and tell them to go away.
