SPRINGFIELD, Ill. (AP) — Springfield Mayor Mike Houston says he will seek another term in 2015.

The (Springfield) State Journal-Register reports (http://bit.ly/1sgjW1m ) that the 70-year-old banker promised to serve one term when he came out of political retirement and won again in 2011. But he says he has been inspired by voters' "continued reassurance and encouragement."

Houston is a Republican but the Springfield City Council is officially non-partisan. Houston served as mayor from 1979 to 1987 but lost a 1986 bid to become Illinois state treasurer.

Sangamon County Auditor Paul Palazzolo (pal-uh-ZOH'-loh) is also a candidate and said Houston is "breaking his pledge" to serve only one term.

Springfield City Treasurer Jim Langfelder intends to run and Alderman Cory Jobe is exploring a possible run in the April 7 election.
