Clinton picked up a number of states, but some of them had been only marginally Republican to begin with. Dukakis nearly won California, Maryland, Illinois, and Pennsylvania - mainstays of the current Democratic coalition. Clinton's strong showing in the South hearkened back to the Carter era and doesn't coincide at all with the states Obama won in 2008.
And more generally, Democrats had been doing well in the Northeast and the west coast for a while, so regionally it was merely the continuation of older patterns.
So I don't see 1992 as a realigning election.
Southern states like Kentucky and Georgia were probably won solely because of Perot.
Georgia maybe, but Kentucky; I don't think so.
