MILWAUKEE — Representative John Lewis, an elder statesman from the civil rights era and one of Senator Hillary Rodham Clinton’s most prominent black supporters, said Thursday night that he planned to cast his vote as a superdelegate for Senator Barack Obama in hopes of preventing a fight at the Democratic convention.
“In recent days, there is a sense of movement and a sense of spirit,” said Mr. Lewis, a Georgia Democrat who endorsed Mrs. Clinton last fall. “Something is happening in America, and people are prepared and ready to make that great leap.”
Mr. Lewis, who carries great influence among other members of Congress, disclosed his decision in an interview in which he said that as a superdelegate, he could not go against the wishes of the voters of his district, who overwhelmingly supported Mr. Obama.
“I’ve been very impressed with the campaign of Senator Obama,” Mr. Lewis said. “He’s getting better and better every single day.”
