So, we have a recent Republican poll showing Brownie ahead by 11 and PPP (Dem-leaning) down by 2.
That means Brownback is ahead by about 4-5 points or so on average.
SurveyUSA had him down by 4 in October and they are likely to poll the state soon ...
Don't know WPA's accuracy, but not a good idea to average an unknown firm with a proven one, no matter what partisanship says.
I'm predicting Brownback wins by a 5-7 point margin - Davis needs to define himself before Brownback does it for him. And if he's portrayed as your average Lawrenceite, he's toast.
