NY Times editorial calls out Obama's negative ways in addition to Clinton's.
'Mr. Obama is not blameless when it comes to the negative and vapid nature of this campaign. He is increasingly rising to Mrs. Clinton’s bait, undercutting his own claims that he is offering a higher more inclusive form of politics. When she criticized his comments about “bitter” voters, Mr. Obama mocked her as an Annie Oakley wannabe. All that does is remind Americans who are on the fence about his relative youth and inexperience.'
