I'll do everyone a favor and tell you that tommorrow Deans numbers will again drop in the Zogby Iowa poll. Fact is, as Zogby pointed out, Dean had his worst day of polling in Iowa of 18%. Yet his numbers for today were 24%, because Zogby looks at multiple days of polling. So, assuming that the Dean numbers don't magicaly jump up in the 24% range again with todays polling, Dean is in for another day of falling Iowa numbers, and most likely will have falling poll numbers till at least Friday.
Perfect Storm? Looks more like a cloudy overcast to me.
