Plurality Wins in the 1968 Presidential Race:
The Impact of George Wallace
Because our electoral system for electing presidents uses
plurality elections on the state level, a strong independent or
third party candidate can have an overall disruptive effect on the
election, splitting votes for other candidates or allowing them to
win with only a plurality of the vote. This is exactly what happened
in 1968 when George Wallace broke with the Democratic Party and ran
as an independent against Republican Richard Nixon and Democrat
Hubert Humphrey. Only 22 states were won by a candidate who received
a majority of the vote. The winner had less than 40% of the vote in
four states � including three states won by Nixon � and the winner
had less than 45% in seven additional states.
Of the 28 states with a plurality winner in 1968, 17 went were
won by Nixon, eight by Humphrey, and three by Wallace. Nixon might
have won some of these plurality victories due to Wallace�s
splitting of the Democratic vote. The traditionally Democratic
states of North Carolina and South Carolina provide good examples.
Nixon�s overall vote in these states was quite low�39.5% and 38.1%,
respectively. The deciding factor in these states seems to have been
Wallace�s strong level of support, which resulted in him winning
more than 30% of the vote in each state. If one can assume that most
of Wallace�s support came from what had been the Democratic base �
including many voters who were conservative, but not ready to
support a Republican -- then it is likely that Nixon won these
states only because Wallace was able to take votes away from
Humphrey. This conclusion is strengthened when one considers that
Nixon lost these two states to Kennedy in 1960.
Besides North Carolina and South Carolina, there appear to be
other states in which Wallace split the Democratic base, enabling
Nixon victories. In Tennessee and Florida, for example, the
breakdown of the vote was similar to that of the Carolinas.
Wallace�s candidacy likely affected outcomes in others states where
he had less support. For example, Nixon had lost Missouri in 1960,
but defeated Humphrey by 1% there in 1968 -- while 11% voted for
Wallace. In addition to Missouri, there were 12 states won by a
plurality of less than 5% of the vote.
