Okay, need further evidence ? How about this characterization of Jim Webb, contained in the Weekly Standard pre-election feature article: "Webb is not only a gifted novelist, but something rarer: a novelist of ideas. And all his ideas are reactionary. Together [his] books form a long, eloquent protest against the wussification of America, exemplified in the Washington world of slick pols, butt-covering bureaucrats, and the panty-waist, nancy-boy journalists who serve as their stenographers." Now, I ask again. Was The Weekly Standard trying to help, or hurt, George Allen with this tribute to his opponent, James Webb ?
These are kinds of criticisms that Hitler leveled at his non-Nazi counterparts as he maneuvered his way to power. If you look up the phrase "blood and soil" on Yahoo, you will find
this Wikipedia listing ranked at number two. It deals with Hitler's blood and soil ideology. On Google, this Wikipedia article is ranked at number one. Like I said, this is no accident - "blood and soil" is merely an indirect way of painting someone as having borderline Nazi tendencies. Not fascist, mind you - Nazi, with all of the exterminationist baggage that entails.
The point is that the crux of the article didn't do anything to rally Allen supporters, or discourage potential Webb voters.
Your esoteric explanation of "blood and soil conservative" may be correct, but only a very small percentage of those who read the article would have picked up on it.
