Romney Keeps Steady Lead in New Hampshire January 6, 2012, 11:51 am Mitt Romney remains the front-runner among Republican primary voters in New Hampshire, while Rick Santorum continues to gain following his strong showing in the Iowa caucuses. In the latest release of the 7 News/Suffolk University tracking poll of likely voters in the New Hampshire Republican primary, 40 percent said they planned to vote for or leaned toward Mr. Romney, 17 percent backed Ron Paul and 11 percent chose Mr. Santorum. Mr. Santorum has increased his share of the vote for the past four days. He started at 3 percent when the poll first began tracking New Hampshire Republican voters one week ago. But Mr. Santorum, the former senator from Pennsylvania, had spent much of his time campaigning in Iowa before the caucus vote on Tuesday, and has steadily attracted crowds during his forays in the Granite State at the end of this week. Newt Gingrich got 9 percent and Jon M. Huntsman Jr. was the choice of 8 percent. Still, four days before the primary, 15 percent say they are undecided. Two-thirds of the voters surveyed said they were unlikely to change their minds before Tuesday's primary, 30 percent are somewhat likely to change their minds and only 2 percent said they were very likely to change their choice before the primary. Among Mr. Romney's supporters, about a quarter said it was possible they could choose another candidate before Tuesday. The statewide survey was conducted Jan. 4 and 5 with 500 likely voters in the New Hampshire Republican presidential primary. The poll of landlines and cellphones has a margin of sampling error of plus or minus 4 percentage points.
