29. 14% undecided, 45% said they could change their minds, and republicans included in this

poll. In addition NH is a partially open primary:

" the New Hampshire primary is not a "closed primary," where voter participation is limited by voters' past or recent party registration. Instead, New Hampshire enables any voter who has been undeclared, or re-registers as undeclared (not registered with any party) to vote in either party's primary. This seemingly technical distinction can have big impacts on the primary, and how fluidly candidates do in the state (especially if only one party has a competitive primary in a given year, eliciting a greater likelihood that undeclared or less partisan voters will flood that party's primary, if they want to participate at all.) This system is not a fully open primary, because people who are registered with a party (Republican or Democratic) on voting day cannot vote in the other party's primary."
