I don't know much about this area, but I understand that some single-issue PACs have had to actively think about how to convince campaigns that they are genuinely single-issue and non-partisan (for example because the PAC's staff or donors might primarily support or be perceived as supporting one party—and because many PACs do exclusively support one party even they don't advertise themselves that way!). It might be helpful to talk to other single-issue PACs, consultants, or lobbyists to about how they manage this issue. This is important because single-issue PACs don't want campaigns or legislative offices to dismiss them as someone who would never want to support them or work with them, or prospective donors who otherwise identify with a party to fear that their donations will only harm that party. > We will prioritize based on election cycles (who is coming up for re-election), how much they've undermined these three measurements, and how close they are to the committees that are supposed to oversee these domains. In this polarized and super-partisan world, people will instinctively find it hard to believe that you really did that whenever you end up on "the other side" from them in a race they care about. So again, I think you'll end up having to consider what you'll tell those people about why your strategy is the best strategy for your issue and how they can be confident that you really followed it.
