Jacob Hummel first ran for the Missouri House of Representatives in 2008, seeking the seat for House district 108. He defeated fellow Democrat Arthur Gansner by earning nearly 86-percent of the votes.^[5] No Republicans chose to run in the November general election, making Hummel's election a mere formality.

In 2010 Hummel was unopposed in the August Democratic primary. In the November general election he defeated Republican challenger Joe L. Rusch by over 2,400 votes to earn a second term in the legislature.^[6]

Due to House redistricting following the 2010 United States Census the former 108th districts boundaries were altered and it was also renumbered as the new 81st District.
