The 2012 Will County Executive election was held on November 6, 2012. Incumbent Democratic County Executive Larry Walsh ran for re-election to a third term. He was challenged in the Democratic primary by Leonard Thompson, a former state Department of Corrections employee, and won renomination with 68 percent of the vote.[1] In the general election, Walsh was challenged by Republican Cory Singer, the President of the Will County Forest Preserve District.
Walsh campaigned on his record in attracting economic development to the county, pointing to G&W Electric's relocation to Bolingbrook.[2] Singer attacked Walsh for failing to advocate for the county during the 2011 congressional districting, and for a lack of progress in establishing county autonomy over any airport constructed in Peotone.[3] Walsh ultimately defeated Singer to win re-election with 54 percent of the vote.
