I means that the underdog has less than a 30% chance of winning.

I had every one of your listed races on my top-tier list, with the lone exception of PA-13 (Hoeffel), which is on my second-tier longshot list.

I did have several races on my top-tier or "tweener" lists that don't appear on yours. Just for comparison/discussion, those would be:

AR-04; CO-04; FL-22; FL-24; IL-19; IN-07; KY-04; MS-03; MN-06; NH-02; NM-01; OH-03; OH-17; PA-18; TX-05
