Below are some excerpts from a News Gazette summary of local election turnout, by Tom Kacich. 

"President-elect Joe Biden got the greatest number of votes by any presidential candidate in the county’s history — 57,028. Part of the reason for Biden’s big number is the county’s population growth and the enormous turnout on Nov. 3 (75.2 percent, or 96,137 of 127,848 registered voters). 
...
"In Champaign this year, Biden outpolled Donald Trump by about 3-to-1, 26,731 to 8,799. In Urbana Biden got 12,653 votes to Trump’s 2,722. In the rural and suburban areas of Champaign County, Trump got 23,757 votes to 17,644 for Biden. That was closer than four years ago, when Trump had 21,614 to 13,810 for Hillary Clinton.
...
"The county results also showed that only about 27 percent of voters cast their ballots in person on Election Day. The greatest number voted in person but before Election Day (43.5 percent), while about 29 percent voted by mail.

"A retabulation of six randomly chosen precincts and an early-voting site as required by the state board of elections turned up no changes in vote totals."
