Rick Santorum's campaign spent no money on online ads before last week's Wisconsin GOP primary, which turned out to be his last chance to prove himself as a viable contender. In fact, while the campaign spent around $1 million on ads all together online, it may have been better characterized by the Super PAC ads attacking him there.
Super PACs like pro-Mitt Romney group Restore Our Future dropped nearly that same amount online in key primary states as Santorum surged in the polls. In fact, the pro-Romney group spent around $800,000 on web ads in to attack the former Pennsylvania senator in Alabama, Illinois, Michigan, Mississippi, Oklahoma, Ohio, and Tennessee, and Wisconsin.
