Final answer:
Stevenson's next strategy is not explicitly stated, but it may include using more positive messaging and engaging with television advertisements or public appearances to counter the negative publicity from opponents.
Step-by-step explanation:
Stevenson's next strategy to build publicity and support for the trial is not explicitly detailed in the provided reference information. However, given the context of campaign strategies of that era, it could involve countering negative associations created by opponents with more positive messaging or engaging with different channels and venues to reach a broader audience.
Opponents such as Nixon were using name association tactics to connect Stevenson with Alger Hiss, a convicted Soviet spy, to sow doubt about Stevenson's political orientation. Additionally, Senator McCarthy's accusations of "twenty years of treason" under Democratic administrations exacerbated this negative publicity. In contrast, Eisenhower used television advertisements that were short, positive, and depicted him as a war hero and family man, which could be a tactic Stevenson might consider replicating or countering.
If Stevenson was to adapt, he may need to craft messages that could easily resonate with the public, perhaps through succinct and emotionally appealing narratives, which could be deployed via television, the emerging dominant medium of the time. Considering the importance of public opinion shaped by media, he might also increase his presence through televised debates or public appearances to offer his narrative directly to voters.
