Mitt Romney is the heavy favorite heading into New Hampshire's Republican presidential primary on Tuesday. Romney, the former governor of neighboring Massachusetts, carries a double digit lead into the New Hampshire primary, forcing a battle for second place between Congressman Ron Paul and former Utah Governor Jon Huntsman in the state. If Romney wins easily Tuesday, he could gain even more momentum ahead of the South Carolina and Florida primaries that will be held at the end of the month. He currently leads in polls in both of those states. Results are expected to begin coming in Tuesday night after New Hampshire voting stations close at 7 p.m. EST.
