The mayor-- who appeared at a conference in Washington, D.C. on Thursday-- told the editorial board at Crain's Chicago Business of his endorsement in the Illinois governor's race.
Incumbent Democrat Pat Quinn was pleased to add Rahm Emanuel's name to his now long list of campaign supporters.
"I was at a wedding with Mayor Emanuel over the weekend. We don't always agree, but we do agree it's important to have a Democratic governor committed to helping Chicago and all the other municipalities of our state," said Gov. Pat Quinn (D-Illinois).
When former Commerce Secretary Bill Daley was in the democratic race, Emanuel said he would support the winner of the March 2014 primary.
Daley bowed out in September, leaving as Quinn's only challenger former CeaseFire director Tio Hardiman.
When the mayor endorsed Quinn on Thursday, it put aside rumors the mayor quietly supported Republican candidate Bruce Rauner-- a wealthy Emanuel friend and former business associate.
Despite the endorsement, Governor Quinn-- who appeared alongside U.S. Education Secretary Arne Duncan at Wheeling High School Thursday morning-- did not appear to be in full support of the mayor's push for mandatory minimum prison sentences for gun offenders.
Quinn wants the sentencing bill to include a ban on high capacity magazines for semi-automatic weapons.
"I support a ban on high-capacity ammunition magazines. I think it's something that should be in the discussion as well," said Quinn.
The governor's push for a ban on high-capacity magazines has stalled momentum in Springfield for Emanuel's mandatory minimum three-year sentences. Gun rights advocates who may have blessed the stiffer penalties will fight any bill with a provision that limited ammo clips.
So while the mayor endorses Pat Quinn's re-election, the two politicians still are not always on the same page.
