Bob Gibbs would definitely be vulnerable against the right type of Democrat (a conservative from Holmes County who is very much a rural candidate isn't an ideal fit OH-7). VA-4 could be competitive in a Presidential year if the Democrats actually ran a strong candidate for a change. NC-9 could well be competitive by the end of the decade. AR-2 could be competitive with a strong Democrat, especially as an open seat. IN-8 is a competitive district, but Crooks proved to be a disappointing candidate (maybe John Gregg or Weinzapfel could run?). CA-16 and CA-21 are potentially competitive districts, but weren't in 2012 b/c of recruiting failures. CA-7 and definitely CA-31 are competitive districts. NV-3 should be competitive throughout the decade, Oceguera turned out to be a pretty weak candidate.
Seats that could be competitive as open seats: NC-3 (tough, but possible with the right candidate), OH-10 (if SC-7 is on here), FL-27, MN-3, WA-8, KS-3, and maybe NM-1.
Miscellaneous: I don't think MD-6, MN-8, OR-5, and AK at-large are competitive districts, tbh. Also, IA-2 is a Dem seat and MN-2 is a Republican one, btw.
Just my thoughts, excellent idea though
