2012 Michigan House of Representatives election

The 2012 Michigan House of Representatives elections were held on November 6, 2012, with partisan primaries to select the parties' nominees in the various districts on August 7, 2012. The Republican Party retained its majority in the House of Representatives despite losing the popular vote.

Rep. Roy Schmidt scandal
State Representative Roy Schmidt was defeated for re-election after assisting in engineering an election-rigging scandal by which he switched from the Democratic to the Republican Party and recruited a straw candidate to run as a Democrat in order to ensure a swift re-election. The scandal ultimately cost him his seat in the House. Speaker of the House James "Jase" Bolger was also implicated in the scandal, and his race for the 63rd district was made competitive because of his role in it. The matter was referred to Ingham County Circuit Court Judge Rosemarie Aquilina, serving as a one-person grand jury, who ruled in August 2013 that neither Schmidt nor Bogler had committed a crime.
