Contribution limits have been lifted in the state's 49th district senate race, according to a Monday announcement.
Funding caps can be lifted in legislative races if a super PAC spends at least $100,000 on the race.
The Liberty Principles PAC, operated by conservative radio talk show host Dan Proft, has reportedly spent $180,093 in the 49th district senate race on behalf of Republican challenger Michelle Smith, meaning the funding caps have now been removed.
Smith is challenging incumbent state Sen. Jennifer Bertino-Tarrant (D-Shorewood).
"By breaking the contribution limits in the 49th District, Dan Proft is now allowing Michelle Smith to receive unlimited contributions from Bruce Rauner and the Chicago billionaires who already fund her campaign through Proft," Bertino-Tarrant said in a statement. "Unlike my opponent, I am proud to have the support of small-dollar donors across the the 49th District along with organizations that represent working families, educators, and small business owners."
