(CNN) Hillary Clinton may still hold a big lead in New Hampshire, but it is next-door-neighbor Sen. Bernie Sanders that makes the biggest jump in a WMUR Granite State Poll out Wednesday.

Clinton is still the overwhelming favorite in the state with 51% support. And despite repeatedly saying she isn't running for president, Sen. Elizabeth Warren garnered 20% support from those polled.

Sanders' campaign aides have confidently said that their candidate can play in all early nominating states, but are wide-eyed about the fact that because of his politics and geographical connection Sanders' best state will likely be New Hampshire.

After announcing his candidacy last week, Sanders visited New Hampshire for a series of events over the weekend. The visit was Sanders' 10th trip to New Hampshire since 2014.
