With two days to go before Super TuesdayÂ’s multistate nominating contests, candidates for both parties campaigned furiously on Sunday, trying to seize votersÂ’ support in the hours before the countryÂ’s attention shifts to the Super Bowl.Weekend polls showed Senator John McCain heading into TuesdayÂ’s Republican contests with a clear lead over his chief rival, Mitt Romney. On the Democratic side, Senator Hillary Rodham Clinton was slightly ahead of Senator Barack Obama, although poll numbers were close to a draw.
The challengers in both parties came out swinging on Sunday. At a campaign stop in Wilmington, Del., Mr. Obama criticized both Mrs. Clinton and Mr. McCain and tried to link his opponents to the policies of the Bush administration, particularly the war in Iraq, which Mrs. Clinton initially supported. “I can offer and clean break from the failed policies of George W. Bush,” Mr. Obama said. “I won’t have to explain my votes in the past.”
