Final answer:
A person considering running for president would most likely commission a benchmark poll to get initial insights into their candidacy's potential, voter issues, and to help shape their campaign strategy.
Step-by-step explanation:
Among the types of polls listed, a benchmark poll would most likely be commissioned by a person who is considering running for president. Benchmark polls are conducted in the early stages of a campaign to get a sense of where the potential candidate stands before they enter the race. These polls provide an understanding of the candidate's initial position, areas for potential growth, and issues that are important to potential voters. This insight helps to shape the campaign strategy and messaging.
Exit polls, on the other hand, are conducted on Election Day to get immediate feedback on how voters have voted. Tracking polls are used during the campaign to monitor changes in public opinion over time, and push polls are executed to influence voters under the guise of polling, often disseminating negative information about opponents. However, for someone just considering a run for the presidency, the foundational information provided by benchmark polls would be the most useful.
