Service Employees International Union has put another $2.5 million into defeating Proposition 32 , a November ballot measure that would alter how political campaigns are financed in California.
The donation came from SEIU's California State Council of Service Employees Issues Committee, according to state records filed on Monday, bringing the total contributions to the No on 32 campaign to about $19.5 million.
Between contributions from its issues committee and from SEIU Local 1000, the union has now kicked in about $3.5 million to defeat the Nov. 6 ballot proposal.
The Yes on 32 campaign has taken in about $4 million so far.
The measure would ban unions and corporations from using payroll-deducted funds for political purposes. It also bans direct campaign contributions by either interest group. Both sides could continue funding independent expenditure campaigns.
Labor unions have made defeating the initiative their top priority because they rely on payroll-deducted member dues to build their political war chests, including money for independent expenditure efforts. Corporations use contributions from executives and funds from their company treasuries to play in politics, so the measure wouldn't hit them as hard.
