Politics[]
As a part of Yankee-settled Northern Illinois, Carroll County became solidly Republican upon that party's formation in the 1850s. Of all the counties won by inaugural Republican Party presidential nominee John Charles Frémont in 1856, Carroll County was to maintain the longest unbroken string of supporting the GOP in subsequent elections. It would give a plurality to every subsequent Republican Presidential nominee up to George W. Bush in 2004, beating by three elections the second longest run of Indiana's Porter County which was to give a plurality to Bill Clinton in 1996.
In that 1996 election Bob Dole won Carroll County by only 1.51 percentage points – the smallest margin by a Republican to that point – and in 2008 Illinois native Barack Obama broke this last remaining GOP streak stretching back to Frémont by carrying the county by 4.80 percentage points. Obama was to repeat his win in 2012 by 1.49 percent, but a dramatic swing to Republican Donald Trump in 2016 saw him win by the largest margin since Ronald Reagan’s 1984 landslide by gaining 59.6% of the vote in Carroll County, scoring slightly higher than George H.W. Bush's victory in 1988 in which Bush won 59.4% of the vote in Carroll County.
The largest margin of victory ever in Carroll County was achieved by Warren G. Harding who won 86.7% of votes in the county during the 1920 United States presidential election.
