Whil I agree with many of the criticisms laid out in this article (not Andrew Sullivan's), there is one flaw with the article , and it's the Post's fault, not thos quoted in the article. The Cato Institute
is a libertarian group, not a conservative group. (They're different, right, Hube?)
Also, one thing to keep in mind: whenever Andrew Sullivan complains about "Christian fundamentalism," that's code for "they won't let me marry my gay lover." If you read his blog, you can trace his anger against both the Republican Party and the Catholic Church to that issue.
