(CNN) - While a new poll shows Hillary Clinton as the favorite among New Hampshire Democrats in a potential 2016 presidential run, the survey indicates the GOP lacks a clear frontrunner in the Granite State.
But the New Hampshire primary is about two and a half years away, leaving plenty of time for the 2016 political landscape to change.
According to the WMUR Granite State poll released this week, 62% of likely Democratic primary voters say they would vote for Clinton if the election were held today, while 8% choose Vice President Joe Biden, 5% support Massachusetts Gov. Deval Patrick and 1% prefer New York Gov. Andrew Cuomo. Nineteen percent say that are undecided.
Among likely Republican primary voters, 21% say they back New Jersey Gov. Chris Christie, 16% support Sen. Rand Paul of Kentucky, 10% choose former Florida Gov. Jeb Bush, 8% favor 2012 GOP vice presidential nominee Paul Ryan, and 6% back Sen. Marco Rubio of Florida.
Sen. Ted Cruz of Texas, former Sen. Rick Santorum of Pennsylvania, and Texas Gov. Rick Perry each receive 4%, while Wisconsin Gov. Scott Walker gets 2%.
Some potential Republican candidates have already put New Hampshire on their summer itinerary. Paul appeared at a fundraiser in Concord in May, and Cruz is set to attend a New Hampshire GOP fundraiser later this month. Two other possible candidates, Louisiana Gov. Bobby Jindal and Rep. Peter King of New York, have also traveled to the state this summer.
On the Democratic side, Biden is set to headline a fundraiser in Maine for New Hampshire Gov. Maggie Hassan in a couple of weeks.
For the poll, the University of New Hampshire Survey Center interviewed 516 adults in the state by telephone from July 18-29. The sampling error is plus or minus 4.3 percentage points.
Included in the survey were 200 likely 2016 Republican primary voters and 190 likely 2016 Democratic primary voters.
