That writer, Max Boot, he's not a real totally conservative writer, he wrote some nasty column. I'm not sure of his total outlook but I believe he acknowledges he is no "social conservative", so why call him conservative at all? Where he is conservative might come down to foreign affairs and I don't think one can define themselves as a conservative in that way. I would say, if you strongly believe in the Constitution is a first step towards being conservative. Anyway, try a news search, there is at least, one article I saw commenting on Max's scorching article.
