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.
It's Super Tuesday for the Republican presidential contenders, and 10 states are holding primaries and caucuses.
Former Massachusetts Gov. Mitt Romney hopes he can firm up his front-runner status — a status that, an NPR analysis shows, has so far involved his campaign and a pro-Romney superPAC burying the opposition with negative messages.
