Voicing opposition to proposed sales tax increase

A “yes” vote on the school sales tax may sound like a reasonable notion if you thought no further than the here and now.
It could take some of the burden off property owners, but for how long? Only one school in Fayette County has publically announced that it would lower property taxes if passed by the voters.
If all districts were on board for lowering property taxes, realistically, could the reduced property taxes last?
