UNEXPECTEDLY: Moderator of Tonight’s Democrat Debate Met With Campaign Teams Yesterday.

But as his time as a CBS correspondent, anchor of Face the Nation and writer for Slate and Time magazine Dickerson has advised Barack Obama to “destroy the GOP,” told Hillary Clinton she was “transparent” on the e-mail scandal, and urged the ultra-liberal Elizabeth Warren to join the 2016 race.

On the other hand, he chided the Benghazi committee for “fighting like cats and dogs” and called CNBC editor Rick Santelli’s rallying cry that inspired the Tea Party movement “clownish.”

Nope, no bias there.
