Matt Yglesias of Slate
Morally-challenged "liberal" blogger who puts partisanship well ahead of simple humanity. Shortly after Andrew Breitbart passed away, Matt Yglesias tweeted this :
Conventions around dead people are ridiculous. The world outlook is slightly improved with @AndrewBrietbart dead.
Yglesias currently covering economics at Slate. That's despite (or because of) the fact that at least when it comes to immigration and economics he's completely intellectually dishonest: he fails to acknowledge all the costs of the massive and illegal immigration he supports. For specific examples, see the dozens of comments I've left at his sites over the years, and for a more general discussion see immigration economics. Yglesias doesn't even understand the concept of finite resources.
