Obama says he needs to do better with older voters

Barack Obama put the best face on his loss in Pennsylvania, saying today that he came from 20 to 25 percentage points down to narrow the gap in a state whose older demographics favored Hillary Clinton.

He also argued that his campaign had laid the groundwork for the fall in a large swing state that the eventual Democratic nominee will need to win.

"Overall we feel good about the work that we did," he said on CNN Radio.

Obama conceded, however, that he still must do a better job reaching out and attracting blue collar, older voters. He said that Clinton's argument that she has more experience "might have more traction" with those voters.

He also denied a Washington Post report that his campaign is considering ratcheting up attacks on Clinton by reminding voters of the scandals in Bill Clinton's administration such as Whitewater.

Obama said that he is committed to a new kind of politics and that the anonymous strategist quoted by the Post was out of the loop. "The Washington Post needs to take that source out of its Rolodex," he said.
