“Coulson was expected to outspend her opponent in the race. As of the most recent filings, she'd raised about $450,000 to her challenger's [Biss] $350,000. “
“Coulson was leading the race to represent the 17th Illinois House district with 25,802 votes to Democrat Daniel Biss' 24,025 votes”
That’s about 50,000 votes. So $16 per voter was spent on a house seat.
