(CNN) - Ad spending by Mitt Romney's campaign, combined with spending by the super PAC supporting his candidacy, so far has accounted for 80% of the total money spent on television ads in states voting Super Tuesday, a report showed Thursday.
Romney's campaign spent $1.3 million on ads running in Georgia, Idaho, Massachusetts and Ohio between January 1 and Wednesday, according to an analysis by Kantar Campaign Media Analysis Group (CMAG), CNN's consultant campaign advertising. The super PAC supporting the former Massachusetts governor, Restore Our Future, spent $3.5 million in Oklahoma and Tennessee, as well as Ohio and Georgia.

The combined total for Romney and his super PAC, nearly $4.8 million, is well above any of the other three candidates in the race for the 2012 GOP nomination.
Winning our Future, a super PAC backing Newt Gingrich, spent nearly $900,000 in Georgia, Ohio, Oklahoma and Tennessee, but Gingrich's own campaign hasn't spent any money on television ads in Super Tuesday states, according to the report.
A similar story is playing out for former Sen. Rick Santorum. While the super PAC supporting his candidacy spent $175,400 on television ads through Wednesday, the candidate's campaign hasn't spent any money on ads in the ten states voting March 6.
On Thursday, Santorum's super PAC - the Red, White and Blue Fund – said it was spending $257,000 in Ohio to run ads hitting Romney for the health care plan he enacted during his tenure as governor of Massachusetts.
Texas Rep. Ron Paul spent $98,800 in Massachusetts through Wednesday, though the candidate's campaign announced earlier this week it would run ads in Washington state, which votes Saturday, and Vermont, which holds its GOP primary Super Tuesday.
