Billionaire J.B. Pritzker has pumped another $20 million into his Democratic campaign for governor, bringing his record self-funding total to $126.5 million with two-and-a-half months to go before the Nov. 6 general election.

Campaign finance reports filed late Saturday night showed Pritzker made his latest out-of-pocket contribution on Tuesday, two days before he was a featured speaker at Democrat Day at the Illinois State Fair.

At the fair’s Republican day, Gov. Bruce Rauner asked a crowd financial for help, warning that he would be outspent by Pritzker by a 3-to-1 ratio though he offered no specifics.

Pritzker, an entrepreneur and an heir to the Hyatt Hotels fortune, is worth an estimated $3.5 billion, according to Forbes. Rauner, an equity investor, has said he is not a billionaire.
