Despite strong support from democrats, Washington voters did not back Initiative 1464. The measure would have required new campaign finance disclosures, limited contributions by lobbyists and government contractors, and imposed a three-year waiting period on lobbying by former public officials and senior staff.

On the other hand, Initiative 735 was approved by 63.84% of voters. The measure will urge the state congressional delegation to propose an amendment to the U.S. Constitution regarding campaign financing. The measure also requests the state to ratify the constitutional amendment once passed by Congress.
