A new poll in New Hampshire tips it over the edge from "Leaning Obama" to "Leaning McCain" in my last five poll average. As a lean, it could still easily go either way, so it doesn't change the "Best Case" scenario for either candidate, but it does increase McCain's lead if you assume everybody gets all of their leaning states.
McCain Best Case - McCain 334, Obama 204
Obama Best Case - Obama 330, McCain 208
And if everybody gets their leans (and Obama gets DC) - McCain 282, Obama 256
