At several polling sites, turnout was strong but tensions were high as voters discovered they were in the wrong place for Election Day voting.

That means voters in these counties — Republicans and Democrats — are now required to cast ballots at assigned neighborhood polling places instead of at any polling place in the county.

For the first time in more than a decade, Williamson County voters were required to cast ballots at their own precincts, instead of being allowed to vote anywhere countywide.
