Clinton's Campaign Has Most In Bank

The reports also uncover trends that can signal strength or weakness. Both McCain's and Obama's reports showed large numbers of small donors, meaning they can return to those donors for more money. Giuliani's and Clinton's reports show donations from large numbers of donors who have maxed out, meaning the candidates must find new sources of cash.

Clinton reached her totals with a big fundraising push during the final week in March, just before the books closed for the quarter. She held a series of gala events that week, and her report showed that they played a critical part. More than a quarter of her money came from donors in three cities where galas were held -- New York, Washington and Los Angeles.

She also had help from 84 "Hillraisers" -- well-connected supporters who each collected at least $100,000 for her campaign.

They included Ron Burkle, a supermarket billionaire who is one of former president Bill Clinton's closest friends; Steve Bing, a Hollywood producer; Steve Grossman, the former chairman of the Democratic Party; and Rep. Nita M. Lowey of New York.

Obama had substantial support from longtime Democratic donors as well, with a hefty portion of his money flowing from titans in his home town, Chicago, such as his national finance chair, Penny Pritzker, a Hyatt hotel heiress, and Paula Crown of the Henry Crown family. The Crowns are worth an estimated $4.1 billion and hold stakes in the Chicago Bulls, the New York Yankees, Hilton Hotels and Rockefeller Center.

But Obama also tapped a surge of support online. His campaign raised $6.9 million over the Internet from more than 50,000 donors, and an additional $3.4 through mail and phone grass-roots efforts.

In the Los Angeles area, where Obama and Clinton have waged a high-profile battle to capture the support of big donors and celebrities, particularly in traditionally liberal Hollywood, Clinton collected $892,950 to Obama's $713,142. The other contenders from both parties raised a combined $1.2 million in that region.

Behind Clinton and Obama in the Democratic field was former senator John Edwards (N.C.), who finished the quarter with $10 million on hand. His finance reports showed that more than $5 million of Edwards's haul -- more than one-third of his total -- was raised from lawyers, a natural base of support because of his successful law practice in his home state.

The other Democratic candidates' fundraising totals are dwarfed by Obama's and Clinton's. Sen. Christopher J. Dodd (Conn.) finished March with $7.5 million in reserve, Richardson had about $5 million in cash, Sen. Joseph R. Biden Jr. (Del.) had $2.8 million, and Rep. Dennis J. Kucinich (Ohio) finished with $164,000.

On the GOP side, McCain, the presumed front-runner, raised the least of the major candidates and had $5.2 million remaining. Sen. Sam Brownback (Kan.) had about $807,000, former Arkansas governor Mike Huckabee roughly $374,000, Rep. Duncan Hunter (Calif.) $273,000, and former Wisconsin governor Tommy G. Thompson about $140,000. Former Virginia governor James S. Gilmore III banked just $90,000.

Giuliani raised about 62 percent of his money from contributors who gave the maximum donation for the primary process. Romney and McCain raised less than half of their funds from those large-dollar donations.

A sizable segment of Romney's haul came from Utah, suggesting that fellow Mormons were significant contributors. Four of the 10 Zip codes from which Romney received the most money are in Utah, and the leading Zip code is home to Brigham Young University, which Romney attended. He raised $2.8 million in the state, more than one-tenth of his total.
