Charts were made from information in the new Public Policy Polling survey -- done between April 9th and 13th of a random sample of 747 New Hampshire voters, with a margin of error of 3.6 points.
Hillary Clinton was the overwhelming choice of New Hampshire Democrats, and Scott Walker was the choice of the state's Republicans by a significant margin. But it really doesn't matter who the Republicans liked, because Clinton easily defeats any of the GOP hopefuls (and by about the same margins). New Hampshire is definitely trending Democratic -- at least as far as the presidency in 2016 goes.
It's also interesting that both the second and third place Democrats (Warren and Biden) also would beat the top Republican in New Hampshire, but not by as large a margin as Hillary Clinton (see chart below).
