Back when Rick Santorum was driving around Iowa in the “Chuck Truck,” the ratio between Mitt Romney’s and Santorum’s respective fundraising hauls was far greater than the ratio between the respective payrolls of the Boston Red Sox and the Pittsburgh Pirates. For every $1 that Santorum raised in 2011, Romney raised $26. In all, Santorum raised $2.2 million that year, to Romney’s $56.5 million. 

That gap has since narrowed dramatically. So far in 2012, for every $1 that Santorum has raised, Romney has raised $1.31 ($13.5 million for Santorum, $17.7 million for Romney). For every $1 that Santorum raised in February alone, Romney raised $1.28 ($9 million for Santorum, $11.5 million for Romney). Moreover, February was not Romney’s biggest fundraising month, while Santorum raised more in February than he had in all previous months of his campaign combined.
