A couple of observations:

A poll this far out is meaningless except to possibly rank various GOP contenders on where their strength is at the moment. The Tea Party/disaffected social conservatives are angry and motivated, so they’ll poll their preferences better for the moment.

That Obama has a mere 4 pt lead over Huckabee tells you that Obama has real problems at this point, and a strong GOP candidate has a good chance of winning in 2012. I don’t think Huckabee is that candidate.

All those figures are simply overwhelmed by the large numbers of undecideds - which throw the worth of the poll out of the window.

Polls like this make for fun blog posts, and little else.
