Which rule for successful ballot initiative campaigns is not proposed by Shaw?

The concept of linking a ballot initiative campaign to a parallel campaign for elective office is not included in the common strategies advocated by Shaw for successful ballot initiative campaigns. Instead, successful campaigns typically emphasize strategies that are directly relevant to the initiative itself, such as grassroots mobilization, reinforcing a clear and concise message that resonates with voters, and building a coalition of diverse supporters who can advocate for the cause.

Focusing on grassroots mobilization allows for more widespread and effective engagement, ensuring that community members feel invested in the initiative. A clear message is essential because it helps to inform and persuade the public about the importance and implications of the initiative. Building a coalition of supporters can leverage various segments of the community, creating a broader base of advocacy and resources for the campaign. Each of these elements contributes to a more robust and compelling campaign strategy that drives voter turnout and awareness, but the link to an electoral campaign is not one of Shaw's recommended rules for ballot initiatives specifically.
