When Rick Santorum suspended his presidential campaign on Tuesday, it offered a rare instance of a positive story for Mitt Romney that knocked President Obama off the front pages.

The same day Santorum exited the 2012 primary fight, Obama delivered his much-feted speech on the so-called ‘Buffett Rule’ at a campaign-style event in Florida.

But the president’s effort to position himself as a middle class warrior against the avaricious super-rich was overshadowed in the coverage of outlets like The New York Times and The Washington Post, as well as this newspaper, by the Santorum news.
