Just making it official.

A Politico reporter who often penned stories about Sarah Palin and other Republicans has quit journalism to work with the Democratic Party in Arizona, sources tell The Daily Caller.

That reporter, Andy Barr, has covered national politics for the publication since 2008. Barr leaving to help elect Democrats will likely fan the flames of critics who say Politico has a liberal bias.

It’s not exactly clear what his new job duties are. Barr wouldn’t say, but told FishbowlDC, which first reported that Barr was leaving, that he left Politico on “very good terms.” That report said Barr, who is from Phoenix, is taking a “political job,” but didn’t say where he is going.

Barr is not the first Politico reporter to leave for a Democratic gig. Congressional reporter Jonathan Allen left Politico in 2009 to work as an aide to Rep. Debbie Wasserman-Schultz, a Florida Democrat, but he returned to Politico in 2010.

Politico’s reporting is sufficiently pro-liberal that another liberal, Greg Sargent of the Washington Post, recently Tweeted:

Law of nature: If the DNC has a really good story to give out, it always goes to Politico #insidegame

So reliably liberal that the DNC rewards Politico rather than the Washington Post or Huffington Post.
