Early returns in TN trending Democratic

I heard from a reporter in Nashville that early votes are heavily Democratic–more than 5 to 1.

About 7500 votes are in from this county, and Nashville is more Democratic than the state at large, but this is still quite a large margin.

We speculated that the heavy Democratic turnout may be caused by the high degree of excitement on that side (and, conversely, disappointment among Thompson faithful), but it was also interesting to learn that Sen. Obama has two offices in TN already while Sen. Clinton has none.

I wonder if those early voters are telling us anything about who may capture Tennessee?
