SPRINGFIELD — Gov. Pat Quinn’s standing on the national stage sagged Tuesday when a prominent Washington, D.C.-based political newsletter tilted the advantage in this fall’s gubernatorial race to Republican Bruce Rauner.

Stu Rothenberg, a political columnist for Roll Call who keeps tabs on all of the nation’s gubernatorial and congressional races, moved his prediction for the Illinois governor’s race from a toss-up to Rauner.

“Many people were writing Democrat Pat Quinn’s political obituary in 2010 just before he was elected governor of Illinois with 47 percent of the vote. Four years later, Quinn’s re-election bid is in rough shape,” Roll Call writer Nathan Gonzales wrote Tuesday in Rothenberg’s blog, Rothenblog.

Quinn’s “best strategy” for the fall is to turn Rauner into “Mitt Romney on steroids.”

“It could work, but to call this race a tossup right now would be understating Quinn’s standing in the race,” according to the blog.

The post also said Quinn’s precarious standing in the polls threatens to be a drag on the re-election hopes of incumbent Democratic U.S. Reps. Brad Schneider, Bill Foster, Bill Enyart, and Cheri Bustos, all targets of national Republicans.
