Actually I think there are structural factors influencing the results of these polls, as I've said before. People in some states just like their politicians more, not to mention to obvious external factors.
Rounds, by the way, will hopefully relieve Tim Johnson of his Senate seat at the next opportunity.
And pigs fly in Virginia!
Yes, no way a Democratic Senator like Tim Johnson that won by 2 points in a soild Republican state would lose to a Republican Governor like Mike Rounds with 73% approval ratings!
