Yikes. This is pretty bad for the democrats if Udall is only tied.
Bad poll, there's no way Obama's approval rating is that low in Colorado. That being said, recent polling has me running very, very, very scared across the board. I suppose it's possible that ACA antics hurt Obama particularly among swingy inter-mountain west voters though.
If this is a bad poll, then all the recent polls are bad polls. Stop the denial please. Republicans suffered a massive blow, and now it's (seems) like its the democrats turn.
