Voters passed a state constitutional amendment paving the way for the Oregon State Legislature and local lawmakers to limit political contributions and expenditures.

Measure 107 also allows for rules regarding disclosure of campaign activity in order to require campaigns to be transparent about who paid for political advertisements.

Currently, there are no contribution limits due to Oregon Supreme Court rulings declaring campaign finance reform to be in violation of the state constitution. Measure 107 is retroactive, but only to legislation passed on or after January 1, 2016.
