Politics

Peoria County, like Champaign County is a reliable state bellwether, having voted for Illinois' statewide winner in every presidential election since 1964. Prior to 1992, Peoria County, like most of central Illinois, was powerfully Republican. Usually, it only voted for Democratic Party presidential 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.
