A couple quotes from the initiative:

(2)(a) A state excise tax is imposed on the privilege of operating
non-tribal electronic scratch ticket machines. The amount of this tax
shall be thirty-five percent of the net win from the operation of the
electronic scratch ticket machines operated by licensed non-tribal
gambling establishments.

Do the tribes pay a 35% excise tax from the net win off of the machines at the tribal casino's?

(b) Ninety-nine percent of the proceeds of the state excise tax
levied under this subsection, after state lottery commission
administrative expenses for operating the system, shall be deposited in
a new account hereby created called the Equal Treatment Equals Lower
Property Taxes Account in accordance with section 8 of this act. All
tax revenues in the account shall be used to reduce the subsequent
year's state property tax levy as provided in section 3 of this act.

Certainly makes sense to me. Sounds like folks are just trying to level the playing field.
