South County Republican Tony Pousosa plans to run for St. Louis County Executive in 2014. The Green Park alderman announced his candidacy Tuesday night.
County Councilman Steve Stenger had announced last month that he will challenge incumbent Charlie Dooley for the Democratic nomination.
That could set up a rematch between Pousosa and Stenger. Pousosa unsuccessfully challenged Stenger for his 6th district council seat in 2012.
