In a sign that the ride really is about to end for Sen. Hillary Rodham Clinton (D-N.Y.), longtime Clinton supporter and House Democratic Caucus Chairman Rahm Emanuel and Democratic Congressional Campaign Committee Chairman Christopher Van Hollen (D-Md.) on Wednesday endorsed Sen. Barack Obama for president. “After an historic primary contest that made our party stronger than ever, the voters have spoken. I have known Barack Obama for years, first as a friend and later as a colleague. I know he will bring about real change and I am proud to endorse his campaign for president,” Emanuel said. Emanuel’s endorsement carries significant weight for the Obama camp, in part because of Emanuel’s long history with the Clintons and because of his high-ranking status within the party. Both lawmakers also hail from Illinois. Van Hollen said Obama would attract new voters to Congressional races by heading the party’s ticket at the top of the ballot. “The enthusiasm, new voters, and Americans’ demand for change has clearly expanded the playing field for House Democrats this fall. Our nominee Barack Obama is inspiring millions of Americans to register to vote and go to the polls,” Van Hollen stated. “I congratulate Senator Hillary Clinton on her outstanding and groundbreaking campaign. She will continue to be a tremendous asset in uniting our Party, electing a Democrat president and helping to grow our Majority in the House.”
