Sen. John McCain raised more than $15 million in March for his presidential campaign, a top performance for the likely Republican nominee that still falls far short of the massive cash gathered by rival Democratic Sens. Barack Obama and Hillary Rodham Clinton. The amount was confirmed to The Associated Press by two campaign officials speaking on condition of anonymity because the numbers have not been made public. One official said McCain intends to accept public financing in the general election - a sum of about $84 million. McCain donors are now being asked to supplement that public financing with donations to the Republican National Committee, with a goal of raising $120 million through a joint Victory Committee. McCain's March fundraising and the decision to seek public financing in the fall are two separate tracks that highlight the superior fundraising by the Democratic candidates. Obama raised $40 million in March, bringing his total so far in the campaign to about $234 million. Clinton raised $20 million for a total of more than $175 million during the entirety of the contest. McCain has raised about $75 million since he began running last year.
