This summary is adapted from a February 25, 2021 News-Gazette article by Debra Pressey.
Unofficial results in the February 23 Primary Election show a low turnout of about 7.5% of 68,189 registered voters in Urbana and City of Champaign Township. (The Primary was held only in Urbana and the City of Champaign Township.)
Aaron Ammons noted that, as of February 24, another 1,300 mail ballots had yet to be returned and will still be counted as long as they were postmarked by Tuesday, so these numbers are unofficial.
