Again, from Insty:
UPDATE: A reader notes that the popular-vote gap has widened, too: 52-47, or 56,783,329 to 52,120,230, for a difference over 4.5 million votes.
Remember when I said that you always add five points to the Republican. Add five to 49-49 and what do you get? 52-47, among others. It doesn’t always work, but it works a lot better than taking the polls literally.
