We would be far more effective at our local levels working to fill them with Tom Tancredos, Ron Pauls and Tom DeLays than raging on with each other over just one (albeit an important one) position.
We can achieve far more effective results, and longer lasting results if we can influence legislation supportive of the conservative cause for freedom and liberty.
We do this by working local campaigns and at the ballot box.
Bingo! You're the only one I've seen make this point, and it is right-on. The Dems in the Senate, plus Lincoln Chaffee, Olympia Snowe, and Chuck Hagel, represent a non-conservative majority. Re-elect Bush, and put about 6 more Republicans (primarily from the open Southern seats) in the Senate, and let's see what happens in the next four years.
Problem with that approach is the RNC of late has been attempting to replace and/or neuter those who don't march in lockstep with the new faction of the party. They've given Ron Paul trouble for years, now Tancredo is persona non grata at the WH. Hard to support a party that stabs it's conservatives in the back.
