Geography, sometimes called 'diversity' at the time, used to be a significant factor in both presidential politics and supreme court appointments, but it hasn't been a big factor in selection for a long time now. Probably the last presidential nominee who made geography a big factor was Dukakis with Bentsen, and that didn't translate in any relevant way. Kerry as well perhaps, and the same applies.
In step with the development of the role in recent decades there's been a significant growth in 'what a nominee can bring in government' as a factor in selection rather than bald electoral considerations, which was a big factor in the selection of Gore, Cheney and Biden.
