Hillary Clinton's campaign raised nearly $47 million in first quarter

Democratic frontrunner Hillary Clinton has filed her first fundraising report to the Federal Election Commission (FEC), and her campaign says that she raised $46.7 million in primary dollars, a record for an opening quarter in a campaign.

She has also spent a sizable amount: among the expenditures is $18.6 million on gearing up for the campaign ahead - voter files for the first four early-voting states - a one-time cost - plus organizers, technology and list-building. Still, Clinton had plenty of cash on hand at the end of the fundraising period, about $28.8 million.

The Clinton campaign says that more than 250,000 contributors representing every state and Washington, D.C. donated, and 94 percent of the donations were $250 or less, with the average donation coming in at just under $145. Sixty-one percent of the donors were women.

Clinton also seems to have the nation's law firms on her side, with the employees of some of the biggest law firms, like Sullivan & Cromwell giving $142,000, and trial lawyer firm Morgan & Morgan giving nearly a quarter million, reports CBS News' Laura Strickler.

Clinton herself made $278,000 in in-kind contributions, mostly to pay staff working with her during the testing-the-waters, including top aide Huma Abedin, campaign manager Robby Mook, and spokesman Nick Merrill). Campaign chairman John Podesta appears not to be getting paid by the campaign - receiving only $500 from time to time for "travel and subsistence" - in total, $3,586. Abedin, however, made $69,263, according to this filing.

Overall, Clinton spent $5.95 million in payroll, associated costs and payroll taxes. According to the Associated Press, there are 343 staffers working for Clinton's campaign. That $5.95 million is more than any of the Republicans (who have filed so far) have spent on his or her entire campaign (Ben Carson and Ted Cruz come close, but no Republicans so far have spent this much).

Jeb Bush's campaign raises funds in record time

The previous record for primary money raised in a candidate's first quarter was set by President Obama's 2012 reelection campaign, which pulled in $41.9 million during three months in 2011.

Can the GOP beat Clinton in 2016?

The fundraising total does not include the money raked in by a number of Clinton-friendly outside groups, like super PACs, non-profit organizations, and others.

Clinton's campaign fundraising may be record-breaking, but its super PAC numbers - which have not been released yet - are not expected to be as robust for the second quarter, a Clinton campaign official told CBS News. Clinton formally launched her campaign in mid-April.
