Sen. Barack Obama has raised more than $40 million in March with the help of more than 218,000 new donors.
The amount is less than the record $55 million he raised in February, but still a sizable amount that sustains his place as the fundraising leader among all presidential candidates.
Clinton is expected to have raised about $20 million in March, but her campaign has not announced any totals. Details of their March fundraising will be made public in official reports filed with the Federal Election Commission April 20.
The Obama campaign reported having nearly 1.3 million donors overall -- a vast network of contributors that the campaign can tap for additional funds in the weeks and months to come.
