PPP only has Braley up by 1. Ouch. That's not a good sign for him. I think he's finished guys.
What's not a good sign for Braley is that this was released by a left-wing group, which means they have not had any better results for Braley than up 1; while there've been plenty of polls showing Ernst up 2-4 points. The volume and nature of polling here is sufficient to say that Ernst is up in the very low single digits (even though for a single poll with such a result is within the margin of error, it's not the case when you have a bunch). Consider that in Colorado, where Gardner is actually polling slightly better than Ernst, Democrats have managed to release two internals showing Udall up three (though, tbf, from less reputable sources than PPP).
When will KCDem be banned?
There've always been hacks who join right before an election, and they always leave right afterwards, even if their party does do well. If nothing is done to permanent hacks (and we all tolerate Dr. Scholl and Krazen and whatnot) it doesn't seem to make sense to go after KCDem and his ilk.
