You can’t fight two parties forever, you must eliminate one of them as soon as possible to be able to devote all your energies to the real monster.
And its’ the Tories that are the easiest pickings as of now.
And yes, I believe the same strategy is needed here, as well. Eventually if you want to achieve power, it’s the only way.
In America, the only sound strategy is for conservatives to take over the GOP, not to create some third party that only helps getting Democrats elected. Allowing Al Franken to defeat Norm Coleman, etc. hasn’t exactly spawned a conservative renaissance.
