Former Congresswoman Debbie Halvorson says she’ll announce by the end of next week whether she’s running again for the U.S. House. She would challenge U.S. Rep. Jesse Jackson, Jr., in the Democratic primary.

Halvorson lost her seat in Congress to Republican Adam Kinzinger last year. But when political boundaries were redrawn, her home was swallowed by the district held by Jackson, a fellow Democrat but longtime adversary of Halvorson’s.

“I’ve decided I didn’t want to keep everybody waiting,” Halvorson said Tuesday. “I want to make my decision by this weekend,” with a public announcement “absolutely” coming the following week.

Halvorson filed initial campaign paperwork with the Federal Election Commission earlier this month. She said volunteers are already circulating petitions to get her on the ballot.

This summer she registered with the state as a lobbyist. Her firm’s clients include the Village of Glenwood, which she used to represent portions of in the Illinois Senate.

Halvorson acknowledged she could be helped if more people entered the primary against Jackson, and she could have her wish. Citing sources, the Roll Call newspaper claimed this week that Chicago Alderman Anthony Beale is considering running for the seat.

A Beale spokeswoman would say only that he’s focusing on his work for the 9th Ward.

A spokesman for Jackson had no comment.
