I don't know, but NBC/CNN would call KErry states instantly, while Bush states would take time. SC, GA, VA, NC, WV etc were all too early to call for a long time, yet close states like MI and PA were called for Kerry as soon as the polls closed.
I'm not sure what you were watching, but MI was not called until the middle of the night and GA was called right now. SC took some time as did MT. NJ was a quick call, which surprised us.
It wasn't that bad.
The other networks all called NV rather than OH. In the end, it didn't matter.
