The Republican National Committee raised a record $35.6 million in August, giving the GOP a financial boost at a time when Mitt Romney's campaign was forced to take out a $20 million line of credit.

The RNC now has $76.6 million in the bank, a source at the committee told CNN.

The cash haul marks the best August on record for the RNC.

The committee has also raised more this year - just over $193 million -- than in any previous election cycle.

"The support and enthusiasm we are seeing from large and small donors ensures we have the resources to fund the gold standard of ground games as we head into the final stretch of the campaign to elect Mitt Romney as the next President" the RNC source boasted.

Formal fundraising reports from the campaigns and their affiliated committees are due to be filed with the Federal Election Commission on Thursday.

The Romney campaign was forced to borrow $20 million in August because, by law, the de facto GOP nominee could not tap his general election funds until after accepting the nomination at the Republican National Convention.

Their August line of credit was first reported Wednesday by The National Review.
