Iowa live results E-37%,C-31,O-27% 38p reports

The first precints are reporting a tight race between Clinton and Edwards, Obama trails at 23%

This is coming from the caucus results page

I suspect this is coming from the smaller rural areas, Obama numbers will likely rise as the urban centers start reporting.  
This thing will be a nail biter.
