Representative David McSweeney (R-Barrington Hills) announced last week that he will not seek reelection. Instead, he said he'll likely be making a 2022 statewide bid for either US Senate against Senator Tammy Duckworth or Secretary of State if Jesse White retires.

He may not be a household name, but Representative McSweeney has been a huge thorn in Republican leadership's side since he first ran for the Illinois House in the 2012 primary.
