important info for people that want to fund the bus: Prop M (business tax reform) contains a poison pill that could kill Prop L (ridehail tax for Muni funding) if they both pass but M gets more votes. only goes one way reject this backhanded political strategy NO on M YES on L
REJECT POISON PILLS NO ON M "If both this ordinance and another ballot measure or measures imposing, amending, or repealing a San Francisco tax measured by gross receipts appear on the same ballot, and this ordinance obtains more votes than the other measure or measures, the other measure or measures shall be deemed to conflict with this ordinance. In such case, the provisions of this ordinance shall prevail in their entirety, and the provisions of the other measure or measures shall be null and void." - Prop M, page 109 YES ON L FUND THE BUS
