* This is why unpopular incumbents prefer multi-candidate primaries…

Alvarez, known by nearly all voters, had 34 percent support, while Foxx had 27 percent and More had 12 percent, the poll showed. An additional 26 percent said they backed another candidate or were undecided.

Only about a third of Democratic voters support her, and a quarter are undecided or clueless, but she’s still leading the pack.

* More…

The poll found a large percentage of voters don’t accept Alvarez’s explanation for her handling of the McDonald case. More than 7 in 10 Democratic voters said they were not very satisfied or not at all satisfied with it. That included 85 percent of black voters, 67 percent of Hispanic voters and 64 percent of white voters. […]

Overall, half of voters in the poll disapproved of Alvarez job performance, while 30 percent approved and 20 percent had no opinion. White voters were split on the question, while 68 percent of black voters disapproved as did 47 percent of Hispanic voters. The error margin for racial and ethnic subgroups is 5.7 percentage points.

30 percent approval.

Whew.

* One more…

Not to be Mr. Obvious or anything, but if Foxx can tightly sew together blacks, unions and liberals she has a very real path in a three-way primary.

* Meanwhile, this is probably a good move by Alvarez…

Cook County State’s Attorney Anita Alvarez slams Kim Foxx after the Foxx campaign launched a radio ad hitting Alvarez over the Laquan McDonald case, saying she failed to charge in the case for 400 days. Alvarez has contended she was working in concert with the U.S. Attorney’s Office in the period between the shooting and the release of the video. “It’s disappointing that Kim Foxx is running attack ads to score political points off the death of a teenager — in a case that Anita Alvarez has already charged after a joint investigation with the FBI and the US Attorney’s Office,” Alvarez campaign manager Mike Carson said in a statement to POLITICO.”

“Maybe Foxx wants to avoid a discussion about her real record of … raising the sales tax and using tax dollars to give out millions in political pay raises to her supporters. It’s time for voters to learn about the real Kim Foxx.” Given that Foxx is Cook County Board President Toni Preckwinkle’s chief of staff, it’s clear team Alvarez plans to lay Preckwinkle’s flip-flop tax hike at Foxx’s feet.”

THIRD CANDIDATE — Running in the three-way primary for Cook County State’s Attorney is Donna More. More announced Tuesday she is launching a month-long TV ad campaign. From More’s camp: “The effort includes a 30 second spot entitled ‘Anita Alvarez Must Go.’ The cable TV schedule that the campaign purchased will have both 30 and 15 second ads running in primetime and daytime … The ads are intended to draw a sharp distinction between the ‘justice delayed, justice denied’ term of incumbent Anita Alvarez and More’s qualifications for restoring the integrity of the State’s Attorney’s Office. Citing Alvarez’ misconduct, one of the ads says, ‘Anita Alvarez must go.’ The other is a 15 second spot that focuses on More’s plan for reducing gun violence.”
