Democrats Win Trifectas in Arizona, Pennsylvania and Wisconsin, Eye Climate Push

Democrats locked up trifectas — the governor's mansion plus both legislative chambers — in Arizona, Pennsylvania and Wisconsin this week, per Rolling Stone. For Wisconsin it's the first unified Democratic government since 2010, for Pennsylvania the first since 1993, and for Arizona the first since 1966. The party also restored trifectas in Minnesota, Michigan and Nevada, states it last controlled earlier this decade.

David Weiskopf, senior policy director at the nonprofit Climate Cabinet, didn't mince words about the scale. He said the six trifecta states together would rank among the world's largest emitters if they were their own country, rivaling Canada and Saudi Arabia. He called it a massive opportunity to make progress.

Wisconsin is the blank slate. It set a 10 percent renewable electricity standard more than two decades ago, blew past it and never replaced it, and unlike most states it doesn't even make utilities plan what kind of power plants they'll build. Erik Kanter, policy director at Clean Wisconsin, expects quick wins on that planning requirement — a nudge toward renewables over aging gas and coal — plus a renewed push on a clean-power mandate for data centers and fresh funding for the Knowles-Nelson conservation program. Weiskopf wants the new legislature to go bigger and chase a 100 percent clean electricity standard, filling what he calls a Wisconsin-sized hole in the Upper Midwest grid.

Pennsylvania's Senate has been where climate bills go to die, with Republican leaders refusing to bring them up for a vote, and the state's huge natural gas and coal industries complicate Democratic consensus. State Sen. Lindsey Williams has introduced appliance efficiency standards every year since 2019 without movement; she thinks next session is different. She and colleagues also want community solar and warehouse rooftop solar laws, plus a $1.5 billion package to rescue transit systems like Philadelphia's. Reelected governor Josh Shapiro pulled the state out of the Regional Greenhouse Gas Initiative but has promised a Pennsylvania-only cap-and-trade system if lawmakers back it, and he's flagged transit funding as a top priority.

Arizona comes with sunshine, wind and a grid already cleaner than the Midwest's, plus Phoenix-area suburbs that mostly run on electric heat rather than gas. But Republicans have effectively barred the state from regulating greenhouse gas emissions or energy use, and climate and water bills keep failing. State Rep. Lauren Kuby of Tempe says reform of the Arizona Corporation Commission, the utility regulator, tops the wish list — directing it to push utilities toward solar, batteries and virtual power plants, and possibly renaming it to swap 'corporation' for 'public utilities.' Two Democrats set to win commission seats make that fight easier, and water policy could finally move in a state where drought keeps biting.
