A former Chicago Public Schools CEO, Vallas said he has $1.82 million in cash on hand after a modest third-quarter of fundraising and a “significant spike” in contributions after the Sept. 30 deadline that has added $782,000 and counting to his campaign fund. By the end of the month, he expects to top $2 million and surge past that once the Nov. 26 filing deadline has passed and petition challenges are done.
