Voting in the August 2 primaries begins July 13 when the Sedgwick County Election Office begins mailing out ballots.
Advance voting ballots are available on request. People can apply up until the Friday before Election Day.
Sedgwick County Election Commissioner Tabitha Lehman urges voters to mail them back quickly.
"They have to be back in our office by 7 p.m. on election night," she says. "We recommend, though, with changes in the postal system, that as soon as you get that, you vote it and return it because it does take some time now."
