Jeb's support has halved since the April ABC/WaPo poll. He was at 20% with an 8 point lead.
The CNN poll shows a similar story, where he's fallen from running 5 points ahead at 17%

I'm really hoping we get a NH poll soon. The most recent one was that Bloomberg poll which showed that Bush had lost his lead even there, but it's unclear whether that was an outlier. If Bush is going to be slotted into the "moderate" niche, then he obviously needs to win NH. If he can't even win there, he's got problems.
