I would suggest they survey their target audience (when they’re in Arizona, ask Arizonans), see what they need the Dems to help with, and then see if they can use their power to help with it.
I know that’s vague, but one of the worst things I could do is arrogantly pretend I know the most important struggles of local working people. Sure, I could just guess, and some of those guesses may be right - perhaps establishing community aid organizations to reduce the impact of financial strain, creating or supporting rent/tenancy unions to help address housing crises, and labor struggles like union industrial action efforts to create better working conditions and reduce injury and death in the workplace, throwing their weight behind existing protests. But if something else is more important to a region (perhaps a local group able to solve a local problem is underfunded or needs an expert to assist), and a political party recognizes and addresses it, that is empowering to the citizens and helps build enthusiastic support for the party, rather than just seeing them as ineffective distant rich people.
