Washington (CNN) Bernie Sanders and Donald Trump maintain wide leads in their respective primary races in New Hampshire, according to a new CNN/WMUR poll conducted by the University of New Hampshire Survey Center.

On the Republican side, Trump continues to hold more than double the support of his nearest competitor, while the race for second and third place remains muddled: Just 6 points separate the second place candidate from the one in fifth place.

Overall, 30% of likely Republican primary voters back Trump, and behind him, the field vying for second includes Texas Sen. Ted Cruz at 12%, Florida Sen. Marco Rubio at 11%, Ohio Gov. John Kasich at 9%, New Jersey Gov. Chris Christie at 8% and former Florida Gov. Jeb Bush with 6%.
