Using a Moneyball approach to elect state & local climate champions

Which political races should climate advocates focus on to get the most bang for their buck? (Hint: not the presidency.)

Episode Summary

Executive Summary: The episode profiles Climate Cabinet, a "Moneyball for climate" organization that uses data to identify under-the-radar state and local races with outsized climate impact. Carolyn Spears explains how they combine winnability, legal climate authority, and cost to target candidates, support them early with money and advice, and track post-election voting. The conversation emphasizes state legislatures, utility commissions, and local power as critical climate battlegrounds often ignored by national politics.

Main Topics: Why state and local races matter for climate (Priority: 5/5): Roberts and Spears argue that most climate-relevant power sits below the federal level, especially in state legislatures, utility commissions, and local offices that control energy, preemption, and implementation. Climate Cabinet’s data-driven targeting model (Priority: 5/5): Spears explains the organization’s "Moneyball" approach: assess political winnability, climate opportunity under legal authority, and cost to win, then direct resources to high-ROI races. Legal structure and campaign support model (Priority: 4/5): Climate Cabinet operates through a 501(c)(3), 501(c)(4), and PAC/527 structure to educate, lobby, and support candidates, providing early money plus policy and governing support. State legislatures and preemption as climate battlegrounds (Priority: 5/5): The discussion highlights how legislatures can both pass climate policy and strip authority from cities and counties, making chamber control highly consequential. Partisanship, endorsements, and climate voting (Priority: 4/5): Spears says the group is climate-first but operates in a partisan reality, using voting records to judge incumbents and supporting a small number of Republicans who vote with climate goals. Key 2024 targets: Minnesota, Michigan, Pennsylvania, Arizona, New Mexico (Priority: 5/5): Spears identifies several swing-state legislative and commission races with major climate leverage, including Minnesota’s fragile majority, Michigan, Pennsylvania, Arizona’s Corporation Commission, and New Mexico primaries. Accountability after election day (Priority: 4/5): Climate Cabinet keeps relationships with electeds after they win, uses lobbying and relationship-building to influence votes, and can withdraw future support if officials backslide.

Key Arguments: Climate policy is mostly determined at state and local levels, so climate donors should stop over-focusing on the presidency and Congress. A "Moneyball" framework works in politics: choose races where the expected value is highest, not just the biggest or most visible contests. Legislative control matters because state governments can preempt city climate action and reshape the policy landscape. Utility regulators and public service commissions are enormously powerful because they control electricity policy and grid decisions. Early catalytic money is especially effective because small donations can meaningfully shape low-budget down-ballot races. The organization is not messaging candidates into a single climate script; it lets them speak to what voters in their district care about while backing them on the climate substance. Accountability is measured by votes, not vibes; incumbent records determine whether Climate Cabinet continues support. Partisanship is real in climate politics: most pro-climate lawmakers are Democrats, though a small number of Republicans do vote with climate goals. Primary elections can be as important as general elections because many Democrats and some Republicans are insufficiently strong on climate. State-level victories can unlock major policy changes, as seen in Minnesota’s clean-energy legislation and Michigan’s climate advances.

Data Points: Year Climate Cabinet founded: 2020 - Organization created to apply a Moneyball model to state and local climate politics. Candidates supported in 2022: 60 - Climate Cabinet worked with 60 candidates in the prior cycle. Top-race win rate in 2022: about 75% - Claimed success rate for its top races in the 2022 cycle. Candidates supported in 2024: 150 - Climate Cabinet says it is more than doubling support this year. Estimated number of elected offices in the U.S.: about 500,000 - Spears says the organization had to build its own office-tracking system because no definitive list exists. Policy records reviewed: over 3,000 policymakers - Climate Cabinet’s team tracks voting records to assess climate performance. Policymakers analyzed in a deep dive: almost 5,000 - Spears cites a broader two-year analysis of legislative climate voting. Democrats with A-plus climate scores: 1,000 - From the broader analysis of nearly 5,000 policymakers. Republicans with A-plus climate scores: 9 - Shows the severity of partisan divergence on climate votes. Largest U.S. presidential race spending: over $10 billion - Used to contrast national campaigns with much cheaper state and local contests. Competitive U.S. Senate race spending: $150 million to $200 million - Used as a benchmark for higher-profile federal races. Climate Cabinet race spending share: less than 1% of comparable federal-race costs - Their targeted races are far cheaper than Senate or presidential campaigns. Typical annual support rate: 10% to 30% of early dollars - Spears says they aim to be catalytic rather than fully finance campaigns. Small-race support range: $5,000 to $8,000 - Lowest-end race size Climate Cabinet gets involved in. High-end race support range: $1.5 million to $2 million - Estimated involvement in top Pennsylvania Senate races. Minnesota candidate legal max: about $90,000 per candidate - Spears cites Minnesota as a high-ROI state because campaign fundraising is capped. Michigan House majority: one-seat majority - Explains why Michigan is a fragile and high-priority target. Arizona Corporation Commission makeup: 5 members: 4 Republicans, 1 Democrat - The lone Democrat is retiring, creating a major opportunity/challenge. Arizona Corporation Commission seats up: 3 seats - Spears notes the commission has three seats in play for the cycle. New Mexico primary date: June 4, 2024 - Climate Cabinet is supporting candidates in a key Democrat-vs-Democrat primary. Candidate doors knocked: 1,000 doors - Arizona candidate Kevin Volk had already knocked this many by mid-March. Texas legislature schedule: 5 months every other year - Illustrates how much power a short-session legislature can still wield. Median state legislator salary in Texas: $24,000 - Shows why state legislator influence is disproportionate to compensation. Median staff count for Texas legislators: 0 to 2 staff - Used to underscore the need for informational support for policymakers.

Pivotal Quotes: ""We use data and data science to identify under the radar state and local races where relatively modest interventions can yield substantial climate progress."" — David Roberts: Introduction to Climate Cabinet’s core mission and strategy. ""Our theory of change is simple... We are looking for a political opportunity... and climate opportunity."" — Carolyn Spears: Spears describes the two-part winnability-and-impact framework used to select races. ""Votes, not vibes."" — Carolyn Spears: A shorthand for Climate Cabinet’s emphasis on measurable legislative behavior over rhetorical alignment.

Implications: Climate advocates may get more climate impact per dollar by shifting attention from federal races to state/local contests, especially legislatures and utility commissions. Data-driven targeting, early money, and post-election accountability could become the model for climate politics.
