(CNN) - California Attorney General and Democratic gubernatorial candidate Jerry Brown appears to be building up his warchest for what will likely be a very expensive general election.
Brown's campaign reports Thursday that the candidate has $20.6 million dollars in the bank for his bid for governor. The campaign also says that Brown's raised $21.4 million dollars since the beginning of the year and has spent a mere $246,000 in 2010. Brown, a former two-term governor from 1975-1983, faces no serious opposition in next month's Democratic primary.
In the battle for California's Republican gubernatorial nomination, former eBay CEO Meg Whitman, a billionaire, has already spent nearly $70 million of her own money. Her opponent, California Insurance Commissioner Steve Poizner, a multi-millionaire, has spent more than $20 million of his money on his campaign.
California holds its primary on June 8.
