Building Legislative Relationships That Last

Everyone in government affairs and advocacy knows strong legislative relationship matters when a high-stakes ask is on the table. The trick is building it long before that moment arrives, and that part of the job comes with very little instruction. Luckily, we just got some from an insider.

VoterVoice sat down with Sathya Mandjiny, Senior Director at Penta to talk about what it actually takes to become a credible, trusted resource on the Hill. Drawing on Penta's new report, Evaluating Credibility in Washington, and her own years on both sides of these conversations, she laid out a practical playbook for earning trust before you spend it. 

Here are the five takeaways we're still thinking about, with the full recording below.

About the Speaker

Sathya Mandjiny is a Senior Director at Penta, where she leads external affairs and outreach to senior policymakers across the legislative and executive branches. She also gathers direct feedback from Hill staff on what works in advocacy and what doesn't, research that informed much of this conversation. A former Political Director for U.S. Senator Ed Markey, she brings firsthand experience managing relationships with more than 150 elected officials and designing statewide legislative advocacy campaigns.

1. Trust Is Earned in Sequence, Not in a Single Meeting

Sathya describes trust as something earned in sequence. You start by being relevant to an office, then prove yourself useful, and over time that builds the credibility, and eventually the trust, that hard asks depend on. There's no precise amount of relationship equity you can calculate before making a difficult ask, but you can check whether the office knows who you represent, understands your issue, and has seen you show up consistently enough that the ask doesn't appear out of nowhere.

And the payoff of that sequence isn't a guaranteed win. As Sathya put it:

"Trust does not guarantee a yes. What it does is create a relationship that can survive a no."

In Penta's interviews, staff described productive, durable relationships with organizations they sometimes disagreed with. Sathya's own story from her lobbying days proves the point: a disagreement with a sponsor on the last day of session, a bill that didn't pass, and a yes to lead co-sponsorship the very next day. That story alone is worth the watch.

2. Start With Their Constituents, Not Your Ask

Starting from zero with an office? Sathya's first move is grounding the outreach in the people the office represents, a principle familiar to anyone running a grassroots or grasstops program:

"Before I contact an office, I want to be able to answer four questions: Who do we represent in this district or state? What is happening for those people on the ground? Why should this particular office care about what I'm bringing to them? And what can we help them understand or solve?"

Then walk in with curiosity instead of a script. Staff told Penta they remember the organizations that asked how they could help. That one question turns a meeting into a partnership, because it lets the office name what it actually needs from you: data, a constituent perspective, technical expertise, or help breaking down a complicated issue.

3. Credible Information Is Something an Office Can Verify

Legislative offices hear competing arguments constantly. What separates the information they act on from the information they file away?

"The strongest information gives them something they can independently evaluate, rather than simply asking them to trust your conclusion."

Show your work: research, measurable outcomes, firsthand experience, a concrete district example. Penta's research found that 69% of policymakers cite news as a resource they use to learn about issues, well ahead of thought leaders, government sources, and industry experts, which means the conversation started long before you entered the room. The question is what you can add that the office doesn't already have. Sathya's ultimate test is refreshingly practical: can the staffer use what you gave them after you leave?

4. The Best Follow-Up Completes a Useful Next Step

Midway through the webinar, we polled the audience: what's the hardest part of building legislative relationships? Getting the first meeting, staying relevant between asks, staff and member turnover, or not enough time? Staying relevant between asks took the top spot, and Sathya's answer was blunt: generic check-ins aren't the fix.

"Between asks, I would focus less on how do I stay in front of them, and more on what can I complete that they might have asked for, how can I clarify or connect, or how can I contribute in a way that makes their work easier?"

Send the information you promised. Answer the question that came up in the meeting. If the office asked to be connected with a constituent or an expert, make that connection happen. And when the office needs something from you, bring the same energy you bring when you need something from them. Staff notice one-way responsiveness, and they remember it.

5. Your Reputation Is Forming Before the Midterms

You don't need to know what the post-election landscape will look like to prepare for it. In Penta's ongoing policymaker interviews, offices are already forming impressions of organizations and industries ahead of the next Congress. That makes this season the moment to act. Sathya's five moves: listen, establish local relevance, fill information gaps, prepare for turnover, and keep the conversation going. Each one fits naturally inside an existing grassroots advocacy strategy.

"The election may change who holds power, but it doesn't reset your organization's reputation to zero. Every useful conversation you have now gives the next conversation somewhere to start."

And if you're starting from zero entirely, Sathya closes the webinar with a five-step plan for your first 30 days. We won't spoil it here; it's in the final minutes of the recording, and it's the most immediately actionable segment of the conversation.

Turn Relationships Into Results

Every takeaway above depends on knowing your advocates, your districts, and your issues well enough to be useful on demand. That's the work VoterVoice was built for: connecting your organization's real constituent voices to the right lawmakers, so the credibility Sathya describes has data behind it.
