There are dozens of additional vulnerable Democrats (or potentially vulnerable Democrats) that you haven’t listed. Off the top of my head, the FL-02 (Boyd), CO-07 (Perlmutter) and MA-06 (Tierney) will be far more competitive than the FL-12, FL-25 or several other GOP districts listed.
Until you have listed 100 Democrat-held House seats, you will not be close to having a “final” list.
FL-2, MA-6 and FL-12 are on our Tier 2 list of possible contenders. At this point about all we have to go on is the ratings of the various races by the "experts". Looking over the list you generally see pretty good agreement between them. But we are looking at other sources and Freeper inputs for guidance. I suspect the troops on the ground are going to see opportunities before our "experts" do see stay in touch and let us know what you hear.
And I agree with you on FL-25. It is not going to last long on our list. We just put it up for everyone to see how the race looked.
