5 points or less doesn't really mean that much and the House is on the verge of flipping, Dems will have a great should TN flip (Bredesen winning). And that is the true bellweather.
Well, I don't think the Ds are going to win in TN or TX (or ND or MO, either....maybe not IN). But the fact that these are the competitive states this cycle says something in and of itself. The only reason the Dems aren't likely to win a Senate majority is the 2018 map. The Republicans had better hope their fortunes improve in '20 and '22 -- or they're almost certainly looking at a brief hold on the Senate, even if they don't lose it this time.
