Mitt Romney and the superPAC supporting him spent more than 15 times as much as Rick Santorum and the superPAC backing him on television ads in Alabama and Mississippi, according to an NPR analysis of data collected by Kantar Media's CMAG unit and reported by the Washington Post.
Santorum won both primaries on Tuesday; Romney finished third in both states.
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.
As advertisers continue to bail from "The Rush Limbaugh Show" after the host called a law student a "slut" and "prostitute," the superPAC supporting GOP presidential candidate Newt Gingrich has essentially doubled down.
Gingrich himself has denounced Limbaugh's remarks, but it hasn't cooled the pro-Gingrich group Winning Our Future.
