Which of the following best describes a tracking poll?

A tracking poll is defined as a continuous measure of support for a candidate or issue over time, which allows pollsters to observe changes in public opinion as events unfold or as the campaign progresses. This type of poll is typically conducted at regular intervals, providing insights into trends in voter preferences. By repeatedly surveying the same population, tracking polls can illustrate how support fluctuates in response to factors such as campaign strategies, debates, or significant news events.

The nature of tracking polls distinguishes them from other survey types, such as one-time assessments, which capture a snapshot of public opinion at a given moment without the ability to show changes over time. Tracking polls are also broader in scope, not limited to comparing multiple candidates or targeting specific groups, such as undecided voters. Instead, they focus on the continuous evolution of support, making them a critical tool for understanding the dynamics of electoral campaigns.
