VALPARAISO, Ind. – Senator Hillary Rodham Clinton managed to co-opt Mr. Obama’s message of hope and optimism, beginning a speech in Valparaiso, Ind., by talking about how positive and “fundamentally optimistic” Americans are.

“We don’t get bogged down and looking back – we’re always looking forward,” she said, as heavy applause nearly drowned out her words. “Whatever obstacle we see, we get over it. Whatever challenge we have, we meet it. We’re the problem-solvers, we’re the innovators, we’re the people who make the better future.”

For the third time since Mr. Obama’s remarks were made public Friday night, Mrs. Clinton criticized him at length, saying his comments seemed “kind of elitist and out of touch.”

“I disagree with Senator Obama’s assertion that people in our country cling to guns and have certain attitudes about immigration or trade simply out of frustration,” she said.

She described herself as a pro-gun churchgoer, recalling that her father taught her how to shoot a gun when she was a young girl and said that her faith “is the faith of my parents and my grandparents.”
