Tell that to Rick Santorum.
Here you go again... Santorum lipped locked himself to the liberal looser sell out Spector and was against a conservative candidate.
It's as plain as the nose on our face. All three 'Pub defections were from states in the deepest of blue regions of the country. In an average election year, a TrueconservativeTM simply isn't going to win these days in those states. The demographics are against us; we simply don't have a broad base of support in those states anymore. The 'Pubs who have traditionally been successful candidates in those states have been liberal-moderate. A TrueconservativeTM who only appeals to the hardcore conservative base will win maybe 10-20 of the vote. We're seeing the same thing happening in places like CA and the Midwest. The demographics have shifted tremendously in the last 10-15 years.
