That was an incumbent victory, non-incumbent victors usually score lower.
Non-incumbent victories since 1932:
2000 Gore - Bush 0.5
1992 Clinton - Bush 6.4
1988 Dukakis - Bush 7.8
1980 Carter - Reagan 9.7
1976 Carter - Ford 2.1
1968 Humphrey - Nixon 0.7
1960 Kennedy - Nixon 0.2
1952 Stevenson - Eisenhower 10.9
1932 Roosevelt - Hoover 17.7
I guess I never realized how close, in terms of popular vote, most US elections have been for the last 50 years.
