| 3 | Broader one: two-thirds for all special taxes; repeal majority taxes like mansion tax | CalMatters Oct 2026 | Corrected | Source: would have "slashed real estate sales taxes statewide" and "revoked taxes that previously passed by a simple majority"; mansion-tax repeal not explicitly stated, removed |
