CHICAGO (AP) — Democratic U.S. Rep. Tammy Duckworth raised more money than any other candidate for U.S. Senate from Illinois last quarter. But Republican U.S. Sen. Mark Kirk has a slim lead in cash to start the year. Duckworth’s campaign says she brought in $1.6 million in the last three months of 2015. She entered 2016 with about $3.65 million cash on hand. Kirk’s campaign says he raised about $1 million in the fourth quarter and has about $3.8 million in his campaign fund for his re-election bid. Duckworth faces former Chicago Urban League CEO Andrea Zopp and state Sen. Napoleon Harris in the March 15 primary. Zopp’s campaign says she raised about $314,000 last quarter and has $714,000 on hand. Harris and Republican James Marter, who’s challenging Kirk, didn’t release numbers Thursday.
