WASHINGTON (CNN) -- John McCain and Rudy Giuliani are tied among Republican voters in New Hampshire, with Mitt Romney in third place and Newt Gingrich showing scant support, a poll released Wednesday said.

The CNN/WMUR New Hampshire presidential primary poll conducted by the University of New Hampshire was carried out March 27 - April 3. (Read full poll results[PDF])

In February, only one point separated the senator from Arizona from the former mayor of New York City; each candidate now has 29 percent.

The latest poll found Romney supported by 17 percent; former Sen. Fred Thompson of Tennessee, 3 percent; and former Speaker of the House Newt Gingrich, 2 percent. Fourteen percent described themselves as undecided.

The poll points to what appears to be a growing gulf between moderates and conservatives in the Granite State. Among people who identified themselves as conservative GOP primary voters, Romney and Giuliani are tied for the lead -- at 24 percent each.

Romney's gains among conservatives appear to have come at Giuliani's expense. The Massachusetts governor gained 11 points among conservatives while Giuliani lost 7 points. But Giuliani is still tied for first overall because he gained 11 points among moderate GOP primary voters.
