Didn't you have the Kolbe seat below numero uno before? :) From 9 or maybe 10, depending on the reading of the oddities coming out of Iowa, to about 23, I don't see much difference. Mix and match. About half of them will more likely than not go Dem however. I don't think the Dems will get much below 23 however, absent a big wave, maybe a couple.
Yes, I had CO-07 in first place before the recent Mason-Dixon poll that put the margin at six, which I think is far more reasonable than the previous 11% Zogby margin or the 17% Survey USA outlier.
PS. I'll decide how far to drop KY-04 once I see the new C-D poll, assuming there's an update on that this week.
