The nation's elite journalists are forever denying that they have a liberal bias. Of course, the evidence in their reporting proves that claim false every day. One other thing belies their claims--the revolving door between the self-described "mainstream media" and Democrats. There simply is nothing like it for conservatives and Republicans looking to get into elite journalism.
The latest example of this phenomenon comes from Beltway insider publication Politico where the revolving door spun both directions on the same day with one reporter leaving the paper to work for Democrats in Arizona and another coming into the paper fresh from a gig working with Senate Democrats.
