Brothers and sisters in arms within the conservative movement are dealing body blows to each other,
is demonstrably wrong. Brothers and sisters in arms within the conservative movement are, despite disagreement over individual issues, united. The problem is that the Republican party has been taken over by "compassionate conservatives", i.e., not-conservatives. The body blows are between conservatives and socialist statists.
You're statement about the Republican Party and statists is further proof of this. My guess is that your "perfect world" outcome and the "perfect world" outcome of these Republican "statists" would be very similar.
But instead of taking the fight to those who have a very different view than you, you take the fight to those who largely agree with you.
The solution is to find a way to achieve unity where we DO agree. We expect the Sunni's, Shites and Kurds to do it in Iraq, yet conservatives are making little effort to do so here at home.
