Prior to 1992, Peoria County usually voted for Republican candidates in presidential elections, only voting for Democratic Party candidates when they won nationally by a landslide. It began trending away from the GOP in the mid-1980s, as evidenced when Ronald Reagan only carried it with 55 percent of the vote in 1984 even as he was winning reelection in a landslide nationally.
From 1992 onward, the county has backed the Democratic candidate in every presidential election, though never by a margin greater than 10 percent aside from 2008 when Illinoisan Barack Obama won it by nearly 14 points. This relative closeness in results was most evident in 2004 when the county backed John Kerry over George W. Bush by only 70 votes.
In the Illinois Senate, Peoria County is represented by Republican Chuck Weaver of the 37th Legislative District and Democrat Dave Koehler of the 46th Legislative District. In the Illinois House of Representatives, Peoria County is represented by Republican Ryan Spain of the 73rd Representative District, Republican Mike Unes of the 91st Representative District and Democrat Jehan Gordon-Booth of the 92nd Representative District.
