Former Massachusetts Gov. Mitt Romney's six primary wins on Super Tuesday didn't come cheap. An NPR analysis shows that last week alone, the Romney campaign and the pro-Romney superPAC combined spent nearly $7 million on TV ads.
Less than $1 million of that was spent by Romney's official campaign, while the pro-Romney superPAC Restore Our Future — which has almost exclusively engaged in negative advertising this year — spent $5.7 million.
That's compared to $220,000 spent on ads last week by the superPAC supporting former Pennsylvania Sen. Rick Santorum.
While it came down to the wire in OH, Mitt Romney was the winner in what was considered the big prize for Super Tuesday. 10 states held their primary events last night with Romney taking 6, Santorum 3, and Gingrich 1.
