I'm not sure if blogs are the sort of thing we are supposed to recommend here, but I want to give a shout out for Victor Davis Hanson. victorhanson.com/
Yes, he is a conservative. What I love about him (well, there are lots of things), is his bounty of historical knowledge, especially of the ancient world, and how he is able to use that knowledge hard won from the past, and turn it into wisdom for us today. He has written history books and historical fiction. And he has insightful commentary on the politics of today. I just think he's smart and wise, and I've learned a lot by reading his essays.
