Darren Bailey, the Republican nominee for Illinois governor, won the primary election on a shoestring budget, raising only $450,938 and spending just $2.30 per vote to defeat his better-funded rivals. Bailey's frugal campaign strategy, which relied heavily on social media and direct mail, was a stark contrast to the millions of dollars spent by some of his opponents in the race.

Why it matters

Bailey's victory on a limited budget highlights the power of name recognition and grassroots campaigning, even in the face of well-funded opponents. However, his success in the primary may not translate to the general election, where he will face the deep-pocketed incumbent, Democratic Governor JB Pritzker, who has spent hundreds of millions of dollars on his previous campaigns.

The details

Bailey raised less than half a million dollars to win the GOP nomination, a far cry from four years ago when he had millions to spend in both the primary and general election. He spent nearly $700,000 to capture over 300,000 votes, or more than 53% of the ballots counted. In contrast, his closest rival, Ted Dabrowski, spent over $2 million and received about 163,000 votes. Bailey's top expenses included $283,392 on direct mail, $177,000 on consultants and staff salaries, and over $31,818 on yard signs.

  • The campaign finance reports covered the first three months of 2026, including the March 17 primary election.
  • Less than 20 days after Bailey's campaign kickoff fundraiser, the chair of the Save Illinois PAC that helped with the event went on to join the campaign of one of Bailey's primary rivals.
