A voter would like to use evidence to determine whether an advertisement promoting a presidential candidate is credible. What actions would best help her achieve this goal?

To determine the credibility of a presidential candidate's advertisement, the voter should fact-check the claims made in the ad using reputable sources, such as fact-checking websites or official government data. Additionally, she should consider the source of the advertisement, including its funding and potential biases. Analyzing the context in which the ad was produced and comparing it with other credible information about the candidate can also provide valuable insights. Lastly, looking for endorsements or criticisms from trusted political analysts can help assess the ad's reliability.
