Short answer? Yes.
Why?
(1) Conservatives make a better, systematic argument for their cause. That is an entirely ancedotal reason (refuted easily by reading Waldo Jaquith and Virginia Centrist), but I think most neutral observers would say conservatives are much better at articulating it’s political philosophy than the left-wing of the Democratic Party.
(2) Liberals who truly believe in the principles of the Democratic Party tend to be way too extreme for Virginia politics, and therefore unpalatable.
(3) The conservative blogosphere seems more “mature” than the liberal one, for no other reason than we have been doing it longer and instinctively look for alternatives to the MSM for our news.
(4) Republicans are socially trained to look for alternatives to the Washington Post and other so-called liberal news outlets. Democrats aren’t, so why bother with blogs, etc.
Just some quick, on-the-fly thoughts. We are in much better shape than the Dems, but the folks at Raising Kaine are right – to what ends?
