For the fifth time, a Northern Kentucky lawmaker will attempt to undo a ban on alcohol sales on election days.Currently, no alcohol can be served or sold while polls are open. Representative Arnold Simpson has filed legislation to scrap the ban four times in the past. And Friday, he will once again present the proposal to an interim legislative committee.Many states originally passed such bans in order to crack down on voter fraud and vote buying. Now, South Carolina is the only other state that still bans alcohol sales on election days.
