39-43 vs. Treasurer Dan Rutherford
40-39 vs. Rep. Aaron Schock
Obviously, lots of Democrats are thinking about replacing Quinn, so Tom Jensen tested Attorney General Lisa Madigan (who has high name rec) and former White House Chief of Staff Bill Daley (who doesn't) as well. Madigan leads Dillard and Rutherford 46-37 and Schock 46-38, while Daley trails Dillard (34-36) and Rutherford (37-38) but edges Schock 40-35.
Madigan has long been mentioned as potential gubernatorial candidate and has a good 48-32 favorability rating overall and a 68-16 score among Democratic primary voters. In a direct head-to-head with Quinn, she trounces him 64-20. Even Daley comes out ahead, too, though, 37-34, which really should give Quinn second thoughts about seeking reelection. But Daley also probably wants to think twice about setting himself on a potential collision course with Madigan, who looks very strong.
Meanwhile, on the GOP side, Rutherford noses Schock 27-26 in a hypothetical three-way primary, with Dillard at 17. He also takes the top spot in PPP's kitchen-sink scenario:
Aaron Schock: 18
Bill Brady: 14
Kirk Dillard: 12
Joe Walsh: 8
Bruce Rauner: 7
Someone else: 7
Not sure: 15
As for the additional names there: Bill Brady was the GOP's 2010 nominee, who barely beat Dillard for the nod and then barely lost to Quinn; Joe Walsh is the infamous loudmouth and soon-to-be-former congressman; and Bruce Rauner is a wealthy private equity titan. As always, these "let's toss everybody into the hopper" polls don't reflect any kind of prediction as to what the primary field will look like, but they do offer a way to judge the initial standing of potential players.
