1972:
Wilson (Democratic) - 37,860,956 (49%) and 365 electoral votes
Heath (Republican) - 36,192,668 (47%) and 173 electoral votes
Thorpe (Independent) - 3,346,825 (4%) and 0 electoral votes
Heath wasn't the political maestro that Nixon was so this may well have happened.
1976:
Thatcher (Republican) - 43,106,896 (49%) and 434 electoral votes
Callaghan (Democratic) - 38,893,424 (44%) and 104 electoral votes
Steel (Independent) - 6,472,662 (7%) and 0 electoral votes
As in the 1979 UK GE, the left raw vote rose compared to the previous election but still lost handily.
1980:
Callaghan (Democratic) - 45,544,072 (50%) and 366 electoral votes
Thatcher (Republican) - 42,668,332 (47%) and 172 electoral votes
Steel (Independent) - 2,454,462 (3%) and 0 electoral votes
Callaghan swept the North and came roaring back in the South, pushing her to within 2-3% in most and winning Alabama and Arkansas. Presumably Thatcherite economics didn't go down well.
1984:
Thatcher (Republican) - 51,239,652 (55%) and 511 electoral votes
Kinnock (Democratic) - 41,855,668 (45%) and 27 electoral votes
Owen (Independent) - 500,810 (0%) and 0 electoral votes
Thatcher back with a bang; Kinnock doesn't have Callaghan's wider appeal. And LOL at Owen.
1988:
Thatcher (Republican) - 63,574,864 (63%) and 535 electoral votes
Kinnock (Democratic) - 36,572,736 (36%) and 3 electoral votes
Ashdown (Independent) - 173,540 (0%) and 0 electoral votes
The good economy shifts the "Ohio man" even more sharply to Thatcher and the Republicans get an avalanche.
1992:
Major (Republican) - 49,267,696 (49%) and 373 electoral votes
Smith (Democratic) - 46,042,584 (46%) and 165 electoral votes
Ashdown (Independent) - 5,242,007 (5%) and 0 electoral votes
Smith made impressive inroads, particularly in the Northeast. Narrow victories in OH, MI, IL, CA and NJ gave the Republicans another term. The bad economic conditions meant that the third-party vote was the highest in sixteen years.
1996:
Blair (Democratic) - 55,410,960 (53%) and 460 electoral votes
Major (Republican) - 48,255,776 (46%) and 78 electoral votes
Ashdown (Independent) - 1,522,862 (1%) and 0 electoral votes
The Democrats win their first election since 1980 on a 'Time for Change' factor, with Blair sweeping pretty much everything but the rural West.
More later.
