Considering all recent polling has shown Durbin up in the high single-digits, it's fair to say that Durbin is most likely up in the high single-digits. He's still quite favored.
I wonder how Republicans will do in House seats in Illinois this year. Dold looks like a definite favorite, and I think Bost's and Schilling's chances, especially the former's, aren't too bad either.
Considering the only "recent polling" is this and YouGov, I'll take that with a pillar of salt.
Oh, and despite YouGov showing Durbin with around the same lead as WAA, they show Rauner doing about ten points worse. So even these polls aren't consistent with each other.
