He wasn't really covering conservatives, he was just going after the powerless freaks (or what the establishment thinks of as freaks). He never took on anyone with any power and in fact before the WaPo he worked for the Soros/Rockefeller-funded TWI and before then he worked for the Kochtopus' own Reason Mag. At the latter establishment, I used to point out that the only public figure he'd dared ask a tough question of was Larry Sinclair, and that continued to hold true during his TWI and WaPo years (er, months).
And, his WaPo gig was actually better for his opponents because he was more constrained there than elsewhere; he's probably going to be able to do more damage to the 'partiers at MSNBC (even if only a few dozen people watch it).
For more, see my posts about Dave Weigel
, which go back to 2006:
1. He's repeatedly misled about one issue in particular, but it happens to be an issue that the establishment has also repeatedly misled about so you won't hear about that from anyone else. Yet, if - unlike Weigel - you endeavor to understand my point and the difference between evidence and proof, you'll see that he's misled about the facts of that matter.
2. He wrote about me on his personal site and then refused to approve a comment I left pointing out how he's wrong. Yes, he's that low.
