OLYMPIA, Wash. -

Washington voters will soon decide whether or not to make the most sweeping changes to the state's campaign finance system in decades.

Supporters of Initiative 1464 say the proposal makes much needed reforms in order to bring more accountability to the system. But opponents say that the measure will use tax dollars to benefit politicians while the state remains under a court order to put more money toward basic education.

I-1464's voucher system would also give voters three $50 "democracy credits" that they can use in state races every two years. To pay for the statewide system, I-1464 would repeal the non-resident sales tax exemption for residents of sales-tax-free states like Oregon and Montana who shop in Washington. To be eligible to redeem the vouchers, participating political candidates would have to pledge to limit self-financing, as well as the size of donations they accept.
