Washington (CNN) - The major super PAC backing Mitt Romney, Restore Our Future, spent almost $21.2 million last month – three times more than the $7 million it raised. The figures were contained in the group's monthly report filed Thursday with the Federal Election Commission.
Overall the group reported it has just under $6.3 million cash on hand.

Among its major donors last month was the founder and executive chairman of GoDaddy.com, Robert Parsons from Scottsdale, Arizona, who gave $1 million. Besides that contribution there were not the kinds of large donations last month like it has seen in the past.
As compared to last month, Restore Our Future spent much more in August than it did in July ($21.8 million vs. $8.2 million) but brought in about just over $400,000 less.
After several weeks off the air, the PAC went up with a $2.2 million ad campaign in Michigan and Wisconsin this week but has not advertised in the other key battleground states since the Republican National Convention.
