The world is atwitter over the Beatle-esque crowd that greeted Barack Obama in Oregon yesterday. But if the most recent polls are to be believed, he's going to need all of them to show up at the polls to salvage a respectable win:

In Oregon, Obama (45 percent) led Clinton (41 percent) by 4 points, with 8 percent undecided and 6 percent refusing a response.

This follows on the heels of the ARG poll I reported on Friday, which also showed Obama ahead by just 5 in the state. These two contrast sharply with previous polls conducted in the state, which had showed Obama leading by 20, 14, and 11 points respectively. Could it be that just like in every other recent primary state, late-deciding voters are breaking to Senator Clinton? Is her mutnemom kicking into overdrive now that even Senator Obama seems to be tossing dirt onto her grave?

There's another nugget worth noting in today's Suffolk polls:

Asked what they would do if their first choice for the Democratic nomination lost, 41 percent of Kentucky Democratic voters said they would still vote for the Democratic nominee; 28 percent said they would jump parties and vote for McCain; 4 percent would vote for independent candidate Ralph Nader; and 24 percent were undecided.

By contrast, Oregon Democratic loyalty ran very strong. Fifty-nine percent of respondents said they would still vote for the Democratic nominee; 19 percent said they would vote for McCain; 5 percent would vote for Nader; and 13 percent were undecided.

Get that? Oregon Democrats show 'very strong' loyalty to the party -- because almost 60 percent will back the nominee of their party, even if it's not their favored candidate. That's the sort of Democratic loyalty that could lead to a McCain landslide.
