The Blogs the Pros Read
This has been floating around for a while, but I ran across it again and decided to post about it for those who read this blog but don't know where to go next, in terms of political blogging on the national level.
The Washingtonian magazine made a list of the blogs that the professional journalists in Washington read and pay attention to. It's a very wide-ranging list, so you can likely find several that suit your poltical orientation. I'm familiar with almost all of them, but only read a handful; another handful I occasionally drop in on. Some, like DailyKos, I never read. But that's just me.
Go take a look and get hooked up.
