There's lots to chew on in the new Newsweek poll:

* Obama and Hillary are locked in a national statistical dead heat among national Dem voters, 42%-41%, with a sizeable 17% undecided, but she has a slight edge among registered Dems, 45%-40%. (It's unclear whether the poll surveyed likely Dem voters.)

* Mirroring other surveys, Obama is winning among blacks, college grads and men, while Hillary enjoys more support among whites, women, older voters and those with a high-school education or less.

* Both candidates' messages seem to have taken hold with the electorate: Obama is seen as the more inspiring candidate by a large majority, while she is seen by many more voters as the candidate with the right experience. Obama has only a slight edge as to which is seen as most likely to make change happen, suggesting that Hillary's efforts to blunt his change message by arguing that you need experience to make change could have born some fruit.

* Despite the acrimony around the contest that has taken hold on blogs and elsewhere, this poll suggests, as do other surveys, that the Dem electorate isn't in the same place. While large majorities feel strongly about their pick, a huge majority of 84% of Dem voters also says it would be happy with either as the nominee.

* On the GOP side, McCain leads Huckabee by a large margin, and, in an interesting finding, more than two thirds of conservatives say they would be happy with him as the nominee, suggesting that all the talk of a conservative rebellion against him may be overblown.
