Many primary races for public office will soon come to an end, and voters have one last day to make a decision.

Tuesday is election day in Kansas, which is the final day for Douglas County voters to cast a ballot for many county, state and federal primary races. Voters have until 7 p.m. to cast a ballot either at their polling site or through advance mail ballots.

In a primary election, registered voters affiliated with a political party may cast a ballot for races within their party. However, registered voters who are currently unaffiliated with a party may declare affiliation on election day, which will allow them to cast a ballot in the party’s primary races. Winners of the primary races will advance to the general election in November.

Some Douglas County polling sites will be different from previous elections because of the ongoing coronavirus pandemic. Previously, Douglas County announced it had to close about 16 polling places because of concerns about the pandemic. Douglas County Clerk Jamie Shew said his office notified about 20,000 voters that their polling site had changed as a result.

The new polling locations are:

• Precinct 2, 3 and 7 — Carnegie Building, 200 W. Ninth St.

• Precinct 4, 5 and 42 — DoubleTree Hotel Convention Center, 200 McDonald Drive.

• Precinct 9, 10, 15 and 21 — Immanuel Lutheran Church, 2104 Bob Billings Parkway.

• Precinct 12, 23 and 24 — First Baptist Church, 1330 Kasold Drive.

• Precinct 14 and 17 — First Presbyterian Church, 2415 Clinton Parkway.

• Precinct 16 and 46 — Arterra Event Gallery, 2161 Quail Creek Drive.

• Precinct 18 and 48 — Rev City Church, 700 Wakarusa Drive.

• Precinct 19 and 47 — Good Shepherd Lutheran Church, 2211 Inverness Drive.

• Precinct 22 and 76 — Connect Church, 3351 W. 31st St.

• Precinct 36, 37, 38 and 77 — Douglas County Fairgrounds, Flory Meeting Hall, 2110 Harper St.

• Precinct 45 and 49 — Corpus Christi Catholic Church, 6001 Bob Billings Way.

• Precinct 57 and 58 — Lecompton Community Building, 333 Elmore St., Lecompton.

Additionally, the county has installed plastic shields between the election workers and voters at polling sites and has provided the staff with personal protective equipment.

Voters who have received an advance mail ballot may also return their ballot on Tuesday. Shew previously said the county saw a massive influx in the amount of requests to vote by mail, likely because of the pandemic.

Those voting through advance mail ballots can cast their ballot either through drop-off locations or through the mail. Advance mail ballots must be returned to drop-off sites by 7 p.m. Tuesday, and all ballots postmarked Aug. 4 will be counted.

The advance ballot drop-off locations are:

• Douglas County Courthouse, South Parking Lot, 1100 Massachusetts St.

• Douglas County Human Services Building, 2518 Ridge Court.

• Douglas County Fairgrounds, Flory Meeting Hall, 2110 Harper St.
