Joe Carter wonders why there is no conservative blog in the top 10, while the Left has Josh Marshall, Atrios, Kos and Kevin Drum, while the libertarians have Glenn Reynolds and Volokh. Actually, Carter wondered why there are no social conservative bloggers in the top 10. I've wondered for awhile now why no conservative blog - social, economic and foriegn policy conservative - is among the 10 largest political blogs.I think the answer is a pretty simple combination of two factors. First, most conservatives probably agree with most of what the libertarians write. The second factor facilitates the first: the major libertarian bloggers don't rant against religion or spend much time promoting their socially liberal views.
The major libertarian bloggers are hawkish on defense and generally support President Bush, so there's a lot for conservatives to agree with. Additionally, even the things libertarians criticise the president for -- spending, protectionism, &c. -- have traction with many conservatives.
Although the major libertarian bloggers occasionally display the stereotypical libertarian distain for religion, they generally try to treat the topic with respect. Why? Possibly because they value the emergent libertarian-conservative blogger coalition and don't want to tear it apart over issues that are, at the moment, less important than the areas of agreement.
