CLAYTON — Mark Mantovani, a retired executive who narrowly lost to Steve Stenger in the 2018 Democratic primary for county executive, said Thursday he is considering another run for the job.

Mantovani, 65, would join a field that includes County Executive Sam Page and County Assessor Jake Zimmerman. Page was selected in April by the County Council to take over as county executive after Stenger’s resignation in a federal pay-to-play sting that sent him to prison.

Page had appointed Mantovani to the regional Board of Freeholders, which is supposed to be meeting to consider potential changes to the region’s governmental structure. But the effort has stalled with a three-month impasse at St. Louis City Hall over the makeup of its delegation.
