Illinois state Sen. Daniel Biss says he won't seek the Democratic nomination for state comptroller in 2016.
The move sets up a potential general election between Chicago City Clerk Susana Mendoza and Republican incumbent Leslie Munger.
Biss, from Evanston, has been a lawmaker since 2011. He tells The Chicago Tribune (http://trib.in/1YpdEdf ) that he wants to avoid an "expensive and divisive battle" for the party.
Monday marks the start of the petition filing period for the March primary.
The 2016 contest is a special election due to the death of Republican Judy Baar Topinka. She died last year after winning another term as comptroller.
