Yup, that'd be 30 seats. I just don't see, now at least, the bulk of those materializing.
My most optimistic has it as follows:
AL-FL, no change
GA, +2 GOP (Burns & Collins)
HA, +1 GOP (Kawananakoa)
IL, +1 GOP (reclaim Crane seat)
IN, no change
IA, +1 GOP (defeat of Boswell)
KS-KY, no change
LA, +1 GOP (defeat of Melancon)
ME-MI, no change
MN, +1 GOP (if Ellison the Muslim gets the nod in the 5th)
MS-ND, no change
OH, +1 GOP (Strickland open seat)
OK-OR, no change
PA, loss of Sherwood, defeat of Murtha (no change)
SC, +1 GOP (defeat of Spratt)
SD, no change
TN, +1 GOP (upset in the 9th by a White Republican)
TX, loss of DeLay seat because of write-in mess, defeat of Chet Edwards (no change)
UT, no change
VT, +1 GOP (Rainville win of open seat)
VA-WA, no change
WV, +1 GOP (Wakim defeats Mollohan)
WI-WY, no change
That would have us gaining 12 seats (14 if Sherwood stays and Dr. Shelley Winters Marla Gibbs wins the write-in), the very "best case" scenario for us with House races. Of course, not likely, but it's good to be optimistic for a change. ;-)
That is an optimistic count. :)
