Joe Klein of Time Magazine
Obsequious hack columnist for Time Magazine. Blogs at their Swampland site. Explicitly supports illegal immigration; almost every other national figure who supports illegal immigration only does so implicitly.
When Barack Obama released an ad containing with an outrageous smear of Rush Limbaugh, Klein only renounced the ad two days later, after Jake Tapper, the New York Times, and several others had pointed out the smear. His renunciation is linked from the eighth and last update to this post.
