To draw the most accurate conclusion about voter turnout in primaries and general elections, the information that is missing from the table is the percentage of Democratic primary voters. Knowing the turnout of both major party primaries would allow for a comprehensive analysis of overall primary voter engagement compared to the general election turnout.
Given the options:
1. The year in which this election took place
2. The candidates running for President
3. The percentage of Democratic primary voters
4. The states of New Jersey and Arizona
The percentage of Democratic primary voters would provide the most direct and useful data for comparing primary turnout to general election turnout across different states, thereby allowing for an accurate conclusion about voter behaviors and trends.
