Hamilton County voters have until Monday, April 6, 2026, to register if they want to cast a ballot in Indiana’s primary election, which will be held on Tuesday, May 5, 2026. Early in-person voting begins Tuesday, April 7. Hamilton County Clerk Kathy Kreag Williams said residents can check their registration status or make changes online through Indiana’s voter portal, using this link. The clerk also noted that 17-year-olds who will be 18 by the November general election are eligible to vote in the primary.

In Hamilton County, one of the highest-profile local races on the Republican ballot is the primary for sheriff. The two candidates are John Lowes, chief deputy of the Hamilton County Sheriff’s Office, and Dustin Dixon, an HCSO lieutenant. Lowes was endorsed by outgoing Sheriff Dennis Quakenbush, while Dixon was endorsed by retired Indiana State Police Superintendent and former Hamilton County Sheriff Doug Carter.

The Republican primary for Hamilton County coroner has changed since the filing period closed. Brad Craig was disqualified by the Hamilton County Election Board in February, leaving incumbent Jeff Jellison unopposed for the Republican nomination.

Another race drawing attention locally is the open Indiana Senate District 31 seat. Republican Sen. Kyle Walker announced in December that he would not seek reelection, creating a crowded contest in both parties’ primaries. Senate District 31 includes Fishers, Geist and parts of Lawrence.

On the Republican side, the candidates are Juanita Albright, Tiffanie Ditlevson, Travis Hankins and Jan Keefer. Albright has served as president of the Hamilton Southeastern school board, Ditlevson is a Fishers city councilor, Hankins is a businessman, and Keefer is an attorney from Lawrence Township.

Democrats running for the Senate District 31 nomination are Andrew Dezelan, Kerry Forestal, Lasima Packett and Catherine Torzewski. Dezelan is a Fishers resident and former longtime policy director for Senate Democrats; Forestal is the Marion County sheriff; Packett is a community advocate and Army National Guard veteran; and Torzewski is a Geist-area Realtor and small business owner.

Hamilton County voters may cast early ballots at the Judicial Center and Hamilton County Fairgrounds in Noblesville beginning April 7, with additional Fishers, Carmel and Westfield satellite locations opening later in the early-voting period. Election Day polling places will be open from 6 a.m. to 6 p.m.
