A person may sponsor only one political committee for the same elected office or same ballot measure per election cycle.  In other words, two committees who have the same sponsor may not contribute to the same candidate or ballot measure committee.  Once one of the committees contributes to a particular candidate, the other committee may not make independent expenditures or electioneering communications benefitting the candidate or who received contributions from the sponsor’s other committee. The same restriction would apply if one of the committees had contributed to a ballot measure committee – another committee with the same sponsor would not be able to make independent expenditures benefitting the ballot measure.  RCW 42.17A.205(5).
