What? There are only 3 Republican seats up for grabs. - The rest are held by Dems.
That is what the author says. I think the author is wrong.
Those three seats are certainly the most vulnerable. But GOP held seats in play include another one in Penn, 2 in Conn., 1 in California, a second one in Colorado, the Delay seat, the Northrup seat in Louisville, the Hyde seat in Illinois, the Heather Wilson seat in New Mexico, maybe the seat the GOP won from Baron Hill in Indiana (I think Hill is running again, or the Chicola seat in the South Bend area), maybe the Taylor seat in North Carolina, the Young and/or Shaw seat in Florida if either retires, maybe the Kennedy seat in Minnesota that he is vacating to run for the Senate. There may be others, but those come to mind off the top.
I don't see the GOP picking up ANY Dem seats, but the Bean seat, the Marshall seat in Georgia, and the Edwards seat might be in play. My guess is that the Dems will hold all three, with the Bean seat the most imponderable at present. The author's list of vulnerable Dem seats is ludicrous. Positing as he does that the seat Strickland is vacating in Ohio to run for governor, CO-3 and LA-03, are in play is well, wishful thinking. The Dems will hold all three easily.
