2012[edit]

The district covered much of the territory previously in the 19th district, and its incumbent, Republican John Shimkus, filed to run in the redrawn 15th.^[4][5] Angela Michael, a retired nurse and anti-abortion activist, ran on a single-issue anti-abortion Democratic ticket.^[6]

2014[edit]

2016[edit]

Shimkus faced no opposition in the general election, after facing a challenge in the Republican primary from Illinois State Senator Kyle McCarter, who had Tea Party backing and funding from the Club for Growth.^[9]

2018[edit]

Shimkus loomed large in the 15th, but finally faced credible (if not well-funded) Democratic opposition from a local teacher and former Obama campaign worker.^[11]

2020[edit]

After John Shimkus announced that he would not seek reelection, Republican nominee Mary Miller and Democratic nominee Erika Weaver emerged as contenders for the open Congressional seat.^[13]
