A Mitt Romney adviser told BuzzFeed about the campaign's coming "two-front attack" on Rick Santorum which "may make previous attacks on Rick Perry and Newt Gingrich look like mere love taps."
Said the adviser: "Santorum's a blank slate, so everyone's projecting on to him what they want because he's the last anti-Romney. Santorum is going to get introduced to people that don't know him."
First, he'll be compared to President Obama: "He's never run anything. The biggest thing he ever ran is his Senate office."
Second, he'll be painted as a creature of Washington: "They're going to hit him very hard on earmarks, lobbying, voting to raise the federal debt limit five times. The story of Santorum is going to be told over the next few weeks in a big way."
