Advocacy and political organizing
In 2025, Diehl helped establish the Oregon Freedom Coalition (OFC), a political advocacy organization focused on tax policy, transportation funding, and government accountability. He serves as the organization’s president.[14] Under OFC, Diehl supported and promoted campaigns opposing large-scale tax and fee increases proposed in statewide transportation legislation.
In June 2025, the Oregon Freedom Coalition launched No Tax Oregon, a statewide referendum effort opposing House Bill 2025, a transportation funding package projected to raise approximately $4 billion in new taxes and fees.[15] The campaign sought to refer the bill to voters and mobilized volunteers to gather signatures across the state.
By late 2025, opponents of the transportation package—including No Tax Oregon—reported collecting more than 150,000 signatures, surpassing the roughly 78,000 required to qualify the referendum for the ballot.[16] Commentators described the rapid signature‑gathering effort as unusually large and fast for a statewide referendum campaign.[17]
