More Sunday Polls

Thanks to Open Left, we can see the early numbers for:

Rasmussen Tracking:
Obama 51%
McCain 45%

Diageo Hotline:
Obama 49%
McCain 41%

My first reaction upon seeing these numbers was worry. Is Obama slipping? But when I then saw DC's post below showing Obama gaining in Research 2000 & Zogby, I stopped worrying?

Why? We may just be seeing some statistical noise today as the polls diverge from each other. Other than that, it's all good today. :-)
