Supporters of Proposition 39 claimed that it will close a tax loophole that currently rewards out-of-state companies for taking jobs out of California and, for tax purposes, treats out-of-state companies the way California-based companies are treated. The savings generated by closing the loophole will be directed to fund public schools and create jobs in the state, especially construction jobs in the clean energy sector.[6][7][8][9][10] Opponents argued that Proposition 39 is simply a tax increase, and it will make out-of-state companies less likely to do business in California.[7][11] The proposition does not affect California-based companies or California residents.[6][7][12][13][14][15]
The primary financial backer of Proposition 39 was Thomas Steyer, who also played a lead role in designing the initiative.[17] California State Senator Kevin de León served as the co-chairman of the Prop 39 campaign.[18]
California State Controller John Chiang appointed three members to a board created to oversee the Allocation of new funds related to the California Clean Energy Jobs Act.[19] The three board members include: Gary Kremen, the founder of Match.Com also a clean technology engineer, entrepreneur and inventor; Erik Emblem, executive administrator and chief operating officer of the Western States Council-Sheet Metal Workers in Sacramento; and Dana Cuff, professor of Architecture and Urban Planning at the University of California, Los Angeles.
