Barack Obama raised $32 million in campaign contributions in January, a record sum that will carry him well beyond next week’s Super Tuesday primaries in what is shaping into a protracted nomination battle with Hillary Rodham Clinton. Obama’s haul was the most raised by any candidate in one month in this presidential campaign. John Kerry raised more — $44 million — in March 2004, but he had already had secured the nomination.

“For a candidate who had no guarantee of getting past Super Tuesday to have raised $32 million in a single month is astounding,” said Massie Ritsch, a spokesman for the Center for Responsive Politics, a Washington nonprofit group that tracks money in politics. “It gives Obama tremendous firepower going into Super Tuesday and beyond.”
