New campaign finance reports show Jerry Brown spent about $36.5 million in his successful bid to become governor of California, a fraction of the $178.5 million spent by his Republican opponent, billionaire Meg Whitman.
In reports filed Monday with the secretary of state's office, Brown's campaign reported spending $29 million on TV and radio ads placed by a Georgia-based Democratic advertising firm, LUC Media.
Whitman, the former eBay chief executive, shows she tapped $144 million from her personal fortune and raised the rest from donors.
The 2010 California governor's race was the highest-spending campaign for statewide office in U.S. history.
Brown was aided by at least $26 million in spending by outside groups, mostly labor unions.
