Know Your Enemy

On the news that independent Chris Daggett qualified for matching funds in his run for governor of New Jersey, Richard A. Lee decided to take a look at three studies examining how independent and third party candidacies have affected the outcomes of duopolized elections. Some excerpts from Lee's summaries with links to the articles:

"Challenges to the American Two-Party System: Evidence from the 1968, 1980, 1992, and 1996 Presidential Elections" by Paul R. Abramson, John H. Aldrich, Philip Paolino and David W Rohde (2000)

In this study, the authors found that independent candidates benefit when voters’ connections with the major political parties are weakened. Moreover, dissatisfaction with the major party candidates – as opposed to their parties – played a greater role in voters’ support for independent candidates. According to the study: “The people supporting an independent candidate are not those harboring a long-developed disaffection from the major parties, but rather are those who can be moved to express anti-party views because, and probably only because, they are disaffected from the parties’ candidates in a particular election.” . . .

"Picking Their Spots: Minor Party Candidates in Gubernatorial Elections" by Steve B. Lem and Conor M. Dowling (2006)

Lem and Dowling examined gubernatorial elections in all states between 1982 and 2000. Their research was designed to determine why minor party candidates run for office when the chances of winning are slim. The authors also suggested that independents can benefit from “ideological gaps” left by the major party candidates. Such gaps create opportunities “to offer something different than the Democrats and Republicans,” they wrote. . . .

"The Origins and Impact of Votes for Third-Party Candidates: A Case Study of the 1998 Minnesota Gubernatorial Election" by Dean Lacy and Quin Monson (2002) . . .

According to Lacy and Monson, as late as mid-October, polls were showing Ventura with just about 10 percent of the vote. But his numbers rose steadily in the latter part of October – so much in fact that on the Sunday before Election Day, the Minneapolis Star Tribune reported that he had a realistic chance of winning the election. The report had a profound and positive impact for Ventura.

“Even though he never officially led in the pre-election polls, the signal communicated to voters through the press was that Ventura was in a position possibly to win,” the authors explained. “In the close three-way race this significantly reduced the incentives to vote strategically. Third party candidates face a perpetual problem of losing their supporters to strategic voting: third party voters often defect to their second most preferred candidate in order to avoid electing their least preferred candidate. With his momentum in the polls and eventual victory, Ventura overcame the usual trend.”
