PPP’s latest look at the New Hampshire primary suggests that Sarah Palin’s endorsement of Republican Kelly Ayotte has driven up the Senate primary candidate’s negatives among moderate voters key to the general election:
Most of the movement both in feelings about Ayotte and in the horse race has come with moderate voters. Moderates make up the largest bloc of the New Hampshire electorate at 47%, and [Democrat Paul] Hodes' lead with them has expanded from just 8 points at 47-39 in April to now 21 points at 51-30. Ayotte's favorability with them has gone from +5 at 32/27 to -19 at 27/46.
The Palin endorsement may well be playing a role in this. 51% of voters in the state say they're less likely to back a Palin endorsed candidate to only 26% who say that support would make them more inclined to vote for someone. Among moderates that widens to 65% who say a Palin endorsement would turn them off to 14% who it would make more supportive.
