Difficulty: HardModels of Voting Behavior

An exit poll asked a random sample of voters in a competitive congressional district to identify the primary factor that influenced their choice in a recent election. The results are summarized in the table below:

Primary Influence on Vote ChoicePercentage of Voters
The candidate's past legislative achievements and economic performance during their term42%
The candidate's campaign platform and promises for future healthcare reforms28%
The voter's desire to support all candidates representing their preferred political party20%
The voter's personal calculation of how the candidate's tax proposals would affect their household budget10%

Which of the following statements is best supported by the data in the table?

  1. A plurality of the surveyed voters made their decision based on the retrospective model of voting behavior.Answer
  2. B
    A majority of the surveyed voters demonstrated prospective voting behavior when making their decision.
  3. C
    Party-line voting was the least common model of voting behavior demonstrated by the surveyed voters.
  4. D
    More than a quarter of the surveyed voters based their decision on the delegate model of representation.

Answer

A plurality of the surveyed voters made their decision based on the retrospective model of voting behavior.
The correct answer is the statement indicating that a plurality of the surveyed voters made their decision based on the retrospective model of voting behavior. Retrospective voting is defined as deciding how to vote based on a candidate's past performance and record. In the table, the largest group of voters (42%) selected the candidate's past achievements and economic performance during their term as their primary influence. Since 42% is the largest percentage among all options, it represents a plurality of the electorate.

Step-by-Step Solution

1
Analyze the table to match each primary influence with its corresponding model of voting behavior.
Past legislative achievements and economic performance (42%) corresponds to retrospective voting; campaign platform and future promises (28%) corresponds to prospective voting; supporting all candidates of a preferred party (20%) corresponds to party-line voting; personal calculation of tax proposals on household budget (10%) corresponds to rational-choice voting.
This categorizes each row in the exit poll data according to the four standard models of voting behavior tested in the AP United States Government and Politics curriculum.
2
Evaluate the quantitative claims in the options regarding pluralities and majorities.
A plurality is the largest single group (here, the 42% group), while a majority must be greater than 50%. Therefore, the 42% group is a plurality but not a majority.
This allows for the validation of the mathematical claims made in the options regarding the distribution of voting models.
3
Differentiate between voter behavior models and congressional representation models.
The delegate model of representation describes how a representative acts on behalf of constituents, which is distinct from prospective voting behavior (even though the prospective voters constitute 28%, which is more than a quarter).
This eliminates the distractor that confuses voting behavior models with congressional representation theories.
