Not entirely. Don't forget Ralph Hall--who may get booted from the Dems anyway (ala Traficant) when he votes for Hastert--and some other Dems hungry for a piece of the pie. Pro-life, pro-2a Rep-elect Lincoln Davis (D.-Tenn.), anyone? Will a man like that want Nancy Pelosi as majority leader?
Any seat that switches to the (R) side--particularly if it's held by a conservative--is good news, since switchers are not likely to switch back, and they tend to get more in line with the conservative legislative agenda.
Plus, it's good to get the numbers up, to save the majority in future elections when things may not go so well. The Senate looks very good for 2004 (Hollings and Miller will likely both retire; maybe Daschle; Boxer, Edwards, Lincoln look vulnerable; Bayh and/or Daschle's seat will be winnable if they run for prez), but we'll need moderate Dem retirements to save us in the House. We won almost all the competitive House seats this year, and they will take a lot of resources to defend, even if Tex. and Ga. have another round of redistricting.
In a word, yes. I'm in an adjacent district and watched the barrage of political ads by this slimeball. Davis is part of the cabal that has helped keep the TN legislature Democrat (through grotesque gerrymandering going back to after the 1970 reapportionment) despite the GOP winning a majority of the vote. He DREW that 4th district seat for himself when Van Hilleary vacated it to run for Governor. He got tons of $$ from the national party (Rangel, et al) and conducted himself like a national Democrat. We had a fantastic candidate in Janice Bowling, but she couldn't match the $$ Davis had nor overcome the Dem edge that Davis had personally seen to. Davis may not be radical left, but he has the ethics of one. I'm personally hoping that Van Hilleary comes back and yanks that seat away from him, we lost a good man with his retirement (and even worse was his loss to a scumbag 'Rat ex-Mayor of mine who bought the Governorship on a pile of lie-ads).
