Wow, this is beginning to look like a "Likely Democratic" race. Johnson is more vulnerable than Mark Kirk.
At this point, Democrats will almost certainly pick up WI, IL and NH. The path for the GOP to keep its Senate majority is getting narrower and narrower...
If 2016 is a strong R year, Kirk, Johnson, and Ayotte will probably hold on, as will most other Republicans.
Anyway, has Feingold even announced whether he's running? I'd like to see some polls of other possible candidates. And Hassan hasn't announced in NH.
As for Illinois, Duckworth's got a scandal brewing, and the Dems could be in for a divisive primary if more candidates get in.
We run strong in Pa; IL& FL; and OH. With or without Feingold.
Duckworth will survive this, and must.
