Were the Voters of Boone County “sold” a bundle of lies?

Below is the advertising circular use to “sell” the PSB sales tax referenda.  Is there any question that the sales tax was to be ended in twenty years, namely 2018?

Please note the ad’s answer regarding will the tax end.  Not a mere “yes” but three “yes’s”

Any excess money from the referendum shortens sunset.  But this did not happen.
