His opponents have been making sure that if he does win, he leaves New Hampshire battered and bruised.
The most recent polls have Romney with as much as a 24-point lead in the state. He has ignored his opponents and stuck to his message.
At one rally in New Hampshire on Sunday, Occupy Wall Street protesters yelled at Romney asking who was to blame for the economy. An irritated Romney confronted the protesters.
"This president has caused a deepening recession and is responsible for 25 million Americans being out of work and (those who have) stopped working are not being able to get full-time jobs," Romney told the crowd. "This president has been a failure and that's one of reason I'm running, is to help you get a job."
Standing next to Romney, New Jersey Gov. Chris Christie stood up for the former Massachusetts governor. "You know, something may go down tonight, but it ain't going to be jobs, sweetheart," Christie told a protester after being interrupted.
In their second debate in 24 hours, Romney was the target Sunday of most of the attacks from the other GOP candidates.
"Can we drop a little bit of the pious baloney?" former House Speaker Newt Gingrich said. "The fact is you ran in '94 and lost. That's why you weren't serving the Senate with Rick Santorum."
Santorum is in line for second place in the primary if the most recent polls hold. He portrays himself as the only conservative with a chance.
There are still many voters who haven't made up their minds. That's encouraging for the other candidates trying to take a bite out of Romney's lead and turn this into a victory.
The South Carolina primary is on Jan. 21
