Howard Dean has weighed in on the mayoral race from Chicago and he’s turned against Rahm Emanuel.

The endorsement comes at a time when the political tides seem to be shift away from the incumbent mayor.

Dean said in a statement:

When I ran for president in 2004, I told supporters in my stump speech that I represented the ‘Democratic wing of the Democratic Party’ — a line inspired by Paul Wellstone that captured the spirit of my grassroots campaign.

Jesús ‘Chuy’ García is running a similar people-powered campaign in Chicago and that’s why I am proud to announce that I am endorsing him as the progressive choice to be Chicago’s next mayor.

Dean also sent out a fundraising email, writing, “In the February 24 primary, the 1% in Chicago raised more than $25 million in an attempt to re-elect the mayor outright and defeat the seven progressive aldermen that Democracy for America endorsed. However, they failed to do so because DFA members like you, working with progressive activists on the ground in Chicago, built people-powered campaigns that overcame millions of dollars in attack ads.”

“That’s a scream!” says Paul Green, Roosevelt University’s Director of the Institute of Politics, alluding to Dean’s famous scream after winning the Iowa caucuses.

“Historically, in mayoral elections, endorsements seldom matter,” Green told the Sun Times.

The Chicago Tribune reports other notable endorsements include Jesse Jackson, Congressman Danny Davis, and former Illinois Senate President Emil Jones, a mentor to Emanuel’s former boss, President Barack Obama.
