With little more than two weeks until Election Day, Illinois Gov. Bruce Rauner’s (R) personal investment in eroding the ranks of legislative Democrats led by House Speaker Michael Madigan (D) has grown to nearly $46 million, the Chicago Tribune reports.

“The massive influx of cash represents the election-year battle lines playing out in Illinois after more than a year of fighting between Rauner, the first-term governor, and Madigan, the nation’s longest-serving speaker, over the future of the state.”
