This is a plea for people not to get too worked up over Zogby's daily tracking. It is the nature of such polls that they wobble around from day to day. Also, try and ignore his leaking of single day samples. The fact is, each day's sample is only of around 400 people. Sampling 400 likely voters gives us about a 10%MoE. Zogby loves to leak little tidbits to try and create a narrative about his tracking polls. Remember his data several days ago that Bush was leading among young voters? That lead quickly disappeared, never to be heard from again.
