Outgoing Sen. Roland Burris may join a long list of contenders for Chicago Mayor Richard Daley’s job.

Supporters for the Illinois Democrat submitted nominating papers to the Board of Election Commissioners for the City of Chicago in time for Monday’s deadline, according to Politico, which said Burris has not decided whether he will run.

Daley said in September that he would not seek a seventh term. Other Democratic contenders in the race to succeed him are former White House Chief of Staff Rahm Emanuel, who served in the House from 2003 to 2009; Rep. Danny Davis; former Sen. Carol Moseley Braun; and state Sen. James Meeks. The mayoral election will be held Feb. 22, and if no candidate tops 50 percent of the vote, a runoff will take place in April.

Former Illinois Gov. Rod Blagojevich (D) appointed Burris to fill the unexpired term of then-Sen. Barack Obama after Obama was elected president. Both Obama and Burris have served as the Senate’s lone African-American Member. Burris did not run for re-election, and Rep. Mark Kirk (R) won the special election to finish the term and the general election for a full term. Kirk will be sworn in Monday.

Burris has run for a number of offices in Illinois. He was elected comptroller in 1978, winning three terms in the office before being voted to the state’s attorney general post in 1990. He also lost a run for Senate and multiple runs for governor.

It also would not be his first run for mayor; he lost a primary to Daley in 1995.
