I think chickenhawk is a fine designation for those who are particularly aggressively warlike and never served like Frank Miller telling OWS to join the military when he never did and Dick Cheney's endless deferments.
I think it's just that: a designation. It's not an argument for or against anything. It's basically just namecalling, and it also assumes a level of knowledge about a person's bravery that is pretty ridiculous to speculate about in all but the most ridiculous of circumstances. It also ignores the possibility of one's willingness to serve being contingent on the action in question. The difference between conscientious objector and coward is largely a product of preexisting ideology.
But really, the main point is that it's useless for purposes of talking about the wisdom (or lack thereof) of a given war. There are cowards and brave men who cheer on every war, and it's not as if people would change their minds about Cheney's positions if he'd happened to have served, which makes it just another tool for partisan rousing.
You apparently think Perry would be a good president if he somehow could get elected so your asessment of Gingich is suspect.
Everything you say about Perry is suspect. But it's moot, because I don't think I've ever said he'd be a good president; just that I think he's right on many issues, and that that ought to matter more. Unfortunately, that doesn't change the fact that communication affects a president's effectiveness. The balance between the two is wildly out of whack, and I've said as much, but that doesn't mean I think pointing this out magically changes it, either.
Gingrich might make a good president or at least not be a disaster. I have a suspicious he would be more moderate and less confrontational than when he was Speaker, but there is no way to know for sure.
Yup, no way to know. I'd expect him to be less confrontational partly because I think he thinks a lot about legacy and would have (presumably) learned a few lessons from past failings, but who knows. All I know is he's a smart, informed guy who likes to focus on policy, and I'd like to see the electorate reward that sort of thing from time to time, even if only with a temporary surge.
