WASHINGTON, D.C. - Republican Mitt Romney has $50.4 million to spend on the final weeks of the campaign, though he still has to pay back $15 million in debt.
 
Romney on Thursday filed documents with the Federal Election Commission showing he raised about $66.6 million in August. He spent $66.4 million. Romney also took out a $20 million loan on Aug. 22. He's already paid $5 million back to the Bank of Georgetown.
 
Romney couldn't spend money raised for the general election until becoming his party's nominee in late August. He used general election money as collateral for the loan. 
 
Romney and the Republican Party raised more than $111 million combined. That was less than President Barack Obama and the Democrats, who raised more than $114 million.
