The President's lead in the polls may be more ephemeral than meets the eye-the Economist reports that its YouGov poll shows Mr. Bush with just a 1 point lead right now and the latest Zogby poll has the President ahead by only two points. The YouGov poll has the largest sample size of all (2,300) and instead of by phone, it is done by email. See page 27 of this week's issue.
