@nimh,
The most populous county from Indiana that is fully in now is St. Joseph, in the north (118,000 voters) - biggest city is South Bend. Narrowly went for Bush in 2004, by 2%. Now went for Obama by 17%!
Biggest swing in Indiana among the fully in counties so far: Dubois county (19,000 voters). In the South, towns called Jasper and Huntingburg. Wasnt Southern Indiana supposed to be hard for Obama, close to Kentucky and all? Well, Dubois county went for Bush by 38% -- GWB got 69% of the vote here. It still went for McCain too - but by just 4%, with McCain getting 51% of the vote.
