2026 midterms could be the end of Pennsylvania’s split legislature, with effects on affordability, election reform, marijuana and more
Pennsylvania has a split legislature, and both chambers are up for grabs in the 2026 midterms.
The 2026 Pennsylvania midterm elections could potentially dismantle the split legislature in Harrisburg, which may have far-reaching implications on various policy areas. Currently, Republicans control the Senate, while Democrats hold the House. If Democrats secure both chambers in the upcoming election, their priorities could shift significantly, particularly in areas such as election reform, marijuana legalization, same-sex marriage, data centers and AI regulation, and affordability.
Election reform has been a long-standing priority in Pennsylvania, with the current Democrat-controlled House advocating for measures such as ballot drop boxes, no-excuse mail-in voting, clear rules for ballot curing, precanvassing, and allowing independents to participate in open primaries. If Democrats maintain control, they may focus on further refining these reforms.
Marijuana legalization has been another key issue for Democrats. Governor Shapiro has included marijuana revenue projections in his budget proposals, and Democrats have pledged to legalize recreational marijuana if they take the Senate in 2026. However, details regarding the dispensary model and social equity measures, such as expungements and license set-asides for minority owners, remain to be determined.
Same-sex marriage equality is often viewed as settled due to the 2015 Obergefell v. Hodges decision, but concerns have arisen following the 2022 overturning of Roe v. Wade. Democrats may pursue a constitutional amendment to explicitly enshrine same-sex marriage rights if they regain control of the General Assembly.
In terms of data centers and AI, the House has previously passed legislation to regulate these areas, including requirements for AI-generated advertisement warnings and measures aimed at energy costs, water use, and local government authority. Democrats are likely to continue addressing these concerns if they win the election.
Lastly, affordability remains a major concern for voters in Pennsylvania. Both parties have taken steps to address this issue, but with different approaches. Democrats have proposed an Affordability Action Plan, which includes property tax and rent rebates, housing protections for underserved communities, increased income tax credits, and food and energy security funding. They have also advocated for raising the state minimum wage to $15 by 2029, with subsequent annual cost-of-living adjustments.
