Sen. John McCain latest financial reports show him in the best financial condition of his presidential drive with $11.6 million in the bank at the end of March.

In a report filed Sunday, the Arizona senator says he raised $15.2 million in March, his top monthly fundraising performance of the campaign. His fundraising still significantly trails Barack Obama and Hillary Rodham Clinton, the two Democrats in the race.

Presidential candidates have until midnight Sunday to submit their March reports. Obama and Clinton aides say they will file later in the day.

McCain refunded donors about $3 million in contributions, most of it money he had received for the general election. The refunds set the stage for McCain to accept about $84 million in public funds for the fall campaign.
