AZ, NH, OH and IA are a waste of money and time, and so is probably FL. All the other races are very competitive, though.
what? That's a tight race if I've ever seen one
No Republican is winning a statewide or federal race in deep blue NH anymore, but that's just my opinion.
Even if that's true, the polls are such that you have to rate it a Toss-Up (or at least Leans D) on any rating system that is claimed to be partially or fully based on polls, or else saying you use polls as a factor is a complete lie.
