Yes, but: That's not the only way Iowans can cast ballots.
By mail
Registered voters may request absentee ballots be sent to them until Oct. 21 at 5pm.
Those who need to register and wish to vote by mail can do so through the Oct. 21 deadline. People may check their voter registration status online or at their county auditor's office.
Ballots will be mailed to voters beginning Oct. 16 and must be returned by mail (postmarks don't count) — or in person at the election office by 8pm on election night.
Early voting
Early, in-person absentee voting will begin Oct. 16 until the day before the election. Registration can be done on-site.
Ballot requests are available at county auditor's offices or special satellite locations and must be completed there.
Polk's election office is located at 120 2nd Ave in DSM and is open Monday-Friday, 8am-5pm.
