Rahm Emanuel continues to lead the Chicago mayoral race, while his nearest rivals compete to join him in the November runoff.

The former White House chief of staff garnered 42 percent of the vote in a new survey commissioned by a branch of the Chicago Teamsters. Former Sen. Carol Moseley Braun (D) was in second with 26 percent of the vote, while former Chicago Public Schools official Gery Chico took 10 percent and City Clerk Miguel Del Valle had 7 percent.

The poll was taken Jan. 4-6, according to NBC Chicago.

A December Chicago Tribune/WGN poll had Emanuel leading with 32 percent.

The mayoral primary is set for Feb. 22. It's a non-partisan contest where the top two vote getters advance to a runoff in April.
