Just because things look bad for Republicans doesn't mean we're out already. In fact, this might help us with MSM and 'Rats underestimating us in election of '08.
It may be. It's easy now to say "I'll never vote for a Republican again," but come election time when your choices are third-party loser, R or D, most will probably go with the R regardless of how much it hurts.
That said, the Republican Party for years has wrestled with being a conservative, small gov't party or a Democrat-lite, compassionate conservative party. Right now, the Democrat-lites appear to be winning; and compromise on issues vitally important to conservatives won't help the party to maintain its base.
Our country's history shows that parties come and go, sometimes on a single issue ... the Republicans could be going.
