Kathryn Hahn is a free agent no longer. Less than two months after NBC axed her freshman comedy, Free Agents, Hahn has nabbed a recurring role on Parks and Recreation as Leslie Knope's new political rival, TVLine reports. Originally written for a male, the original casting call described the character as charming, popular and "more than a bit dim." The worst part? The opponent is heir to the Sweetums fortune, which means Leslie's opponent for Pawnee City Council is beloved by the town. In addition to introducing Leslie's new rival, Parks and Recreation is also bringing back her cop ex-boyfriend, Dave, played by Louis C.K. The Louie star appeared in several episodes early in Season 2 before his character was transferred to San Diego. Hahn's first episode will air in early 2012, as will Louis C.K.'s return.
