Mark Blumenthal studies yesterday's polling:

Today's results may represent a momentary high water mark, given some of the surprisingly positive results for Obama released yesterday, but it's worth taking note of Obama's current dominance on the electoral map. Our strong Obama classification (typically involving leads of eight points or more) now accounts for 268 electoral votes, just two short of the 270 needed to win. We show another four states, representing 38 more electoral votes, in lean the lean Obama column, for a total of 306. And Obama has a nominal lead in five of the remaining seven states classified as "toss-ups."
