Its difficult to tell whether or not this is good news. In 2004, san juan county went 2 to 1 for bush. Hence, its a deep red county. You’d like a big turnout provided it stays in a ratio of two to one for mccain. There are significant numbers of D’s in that county that voted for Bush in 2004.
The is a large party ID gap in early voting for the D’s. Probably around +12% nationally. It is also heavily african american. If Hotline is correct that the early voting results are only 51-46 for Obama, then McCain is in excellent shape.
