The latest Rasmussen poll has Obama within five points — though I’d caution, as usual, against making much of a single poll.

The RealClearPolitics poll average (which doesn’t yet include today’s numbers) has Hillary up 16.

The real question here is what margin Hillary needs to stay credible, and to make her case that primary results demonstrate real general election weakness. 5 points? 10 points? 15 points?

UPDATE: As I said, watch the average. Another poll out today has her up 12.
