Restore Our Future, a U.S. political action committee supporting Republican presidential candidate Mitt Romney, started this month with about $16 million in cash – – 26 times more than its chief competitor’s camp.

Red White and Blue Fund, the super-PAC supporting former U.S. Senator Rick Santorum of Pennsylvania, raised $2.1 million in January and finished the month with $626,607 to spend. Even so, the PAC has continued to raise money in February and today announced an additional $600,000 advertising buy in Michigan, Romney’s birthplace and the site of a Feb. 28 primary.
