Dixon mayor Li Arellano has decided not to run for the 45th Senate District seat, which includes Earlville, Leland, Mendota and Sandwich.
The seat is now held by Sen. Tim Bivins, R-Dixon, who decided in June against running for another term. In September, State Rep. Brian Stewart, R-Freeport, announced his bid for the seat.
"In the months since I announced my intent to run, there have been a number of changes at both the city of Dixon and within my businesses," said Arellano in a press statement. "As a result, the demands on my time have increased as I address several new challenges.
"Those challenges, combined with my appreciation for Brian Stewart as a capable candidate, led me to decide that a long primary battle was not the best choice in this race."
The 45th Senate District of Illinois is made up of all or portions of Jo Daviess, Carroll, Whiteside, Stephenson, Lee, Ogle, Winnebago, DeKalb and La Salle counties.
