Obama Campaign Says Romney Needs To Win Big In New Hampshire WASHINGTON - President Barack Obama's presidential campaign is trying to set the bar high for Republican front-runner Mitt Romney's campaign in New Hampshire. Obama campaign manager Jim Messina said Wednesday that Romney must "win by 30 points or so" in New Hampshire to build momentum for his campaign. Though Romney won the Iowa caucuses with just 8 votes, he has held a wide lead in New Hampshire over his Republican primary opponents. He was governor of neighboring Massachusetts and owns a home in New Hampshire. Obama's campaign is trying to raise expectations for Romney for the Tuesday primary after Romney's narrow victory over former Pennsylvania Sen. Rick Santorum. Obama campaign officials said the Iowa results make Romney a weak front-runner.
