I do think there is a strategic difference between “holding the line” if you have a slim majority (i.e., enforcing discipline on the wavering), in which case you can let a Specter ONCE IN A WHILE vote his “conscience,” vs. keeping a core of committed conservatives who go on the attack at all times. Once you are in the minority, you have to fight like you’re going to be exterminated, because that’s exactly what the libs have in mind.
