John McCain, the presumptive Republican nominee, reported raising $11.7 million last month and borrowng $950,000.
As of Jan. 31, McCain had nearly $3 million in cash to spend as he moves into general election mode, his campaign said in its filing with the Federal Election Commission. After he emerged as the front-runner, he raised more in January than the $6.8 million he collected in the previous three months combined.
For the entire campaign, he has brought in about $49 million and borrowed nearly $4 million. Those figures, however, are less than half those for the leading Democrats.
Barack Obama is expected to report raising $36 million during January, the biggest single-month total during a competitive primary. The flood of campaign cash, most of it raised online, enabled him to air ads in the 22 states that voted on Super Tuesday and in the 10 contests since -- all of which he has won.
Democratic rival Hillary Clinton is expected to say she brought in about $13.5 million. She also loaned her campaign $5 million, and her camp has said it raised $15 million online this month. Both she and Obama are well past the $100 million mark for the campaign.
The presidential candidates now must report their fund-raising and spending monthly.
