After Politico reported yesterday that GOP insiders did not consider Sarah Palin a competitive presidential candidate, Palin attacked Politico in an email to The Daily Caller. Today, Politico executive editor and co-founder Jim VandeHei, one of the authors of the piece, responded. From the November 1 response in the Politico blog On Media:

“We have promised since the earliest days of Politico to pull back the curtain on how Washington really works and to let readers inside the conversations taking place among the people in power. Sometimes that requires extensive use of anonymous sources.

”This is what GOP insiders in this city are talking about and their concerns are widely known, if not publicly discussed. None of these Republicans would speak on the record for obvious reasons: they fear the backlash from Palin and her very passionate supporters around the country.
