I have no doubt that party-over-principle Republicans would endorse a "REPUBLICAN" Kerry/Lieberman ticket if the only other major-party alternative was an Obama/Gore Democrat ticket. "Lesser evil", and the need to "win" would be the rallying calls, and we would similarly be lambasted for our stubborn refusal to be "pragmatic".
I agree with your comments/comparisons, and I welcome seeing others make them. Good call.
