Twenty-two candidates filed to run in the special election for former Rep. Jesse L. Jackson Jr.’s seat before Monday’s deadline.

Every previously announced top-tier candidate filed his or her signature petitions for this heavily Democratic district on Chicago’s south side: Alderman Anthony Beale, former Rep. Debbie Halvorson, former NFL linebacker Napoleon Harris, state Sen. Toi Hutchinson, Cook County Chief Administrative Officer Robin Kelly and former Rep. Mel Reynolds.

Additionally, health care executive Joyce Washington filed to run in the Democratic primary. She was a statewide candidate in 2002 and 2004.

In the coming weeks, election officials will confirm each candidate has the requisite signatures on their petitions — about 1,300 valid names for Democrats. The primary is scheduled for Feb. 26.

Seventeen Democrats submitted their signature petitions, plus five Republicans, including conservative analyst and radio host Lenny McAllister. Democrats are expected to easily hold the seat. Jackson resigned from the House in November amid a federal investigation and after a prolonged absence for health troubles.
