George HW Bush won 421 EV's in 1988 with a 7.7% margin. While Clinton in 1996 won 379 EV's with a 8.5% margin.
The elections of 1984, 1988 and 1992 were among the most uniform I think in terms of state by state percentages. By 1996 divisions were starting to open up.
By the way, even though all 4 minority presidents (Adams 1824, Hayes 1876, Harrison 1888, Bush 2000) were Republican or equivalent, it looks like, if 2012-2016 swings are consistent state to state, that in 2016 a Republican might win the popular vote and lose in the electoral college.
