According to ABC’s preliminary New Hampshire exit poll, 49% of voters were registered Republicans, 47% of voters were independent/undeclared, and 3% were not registered at all. So it seems only 1% were registered Democrats. That is a very odd poll. I’m guessing of the six that voted for Haley, 3 were registered Republicans and 3 were independent/not declared.
