Williamson County's local election is here.

On Aug. 4, voters will head to the polls to cast ballots for over a dozen local offices, from judges and county commissioners to county school board members and county mayor. Early voting runs July 15-30, and all registered voters are eligible to get a head start on voting.

Here's what to know about voting in Williamson County.

Early voting:Tennessee Aug. 4 elections starts Friday. Here's what you need to know

This is the general election for several countywide races. Many candidates are running unopposed following the county's partisan primary election in May.

Voters will also choose candidates in partisan primary races for federal and statewide offices:

Certain statewide judges are not directly elected by voters but appointed by the state governor. Voters are still able to decide whether those judges should remain in office through judicial retention questions.

Judicial retention questions for the Tennessee Supreme Court, the Tennessee Court of Appeals, and the Tennessee Court of Criminal Appeals will appear on the August ballot. Since these judges are not elected, one way to determine their ideology is to check which governor appointed them.

Any Williamson County resident over 18 years old who registered to vote at their current address by July 5 can vote in the Aug. 4 election. To check voter registration status, visit tnmap.tn.gov/voterlookup.

If you are not eligible to vote in the August election, be sure to register ahead of the federal election in November. The deadline is Oct. 10, and registration can be completed at ovr.govote.tn.gov.

Voters must bring a valid state ID to vote.

Voters who wish to vote absentee may request an absentee ballot at williamsoncounty-tn.gov/614/absentee-ballot-request-form.

Where is my polling place?

The Tennessee Secretary of State's website provides a polling place finder tool at tnmap.tn.gov/voterlookup.

County voters can also vote at county voting centers regardless of assigned precincts. Note that the seven voting centers for early voters are not the same as the 25 for election day voting. For example, the Williamson County Election Commission's headquarters is a voting center for early voting but not election day voting.
