WASHINGTON (AP) - The latest financial filings for the presidential campaign show that the "super" political committees supporting GOP candidate Mitt Romney and his party are widening the money gap over pro-Democratic Party organizations.
The main pro-Romney super PAC, Restore Our Future, reports raising $8 million in May, giving it a total of $64 million so far.
A political committee backing Obama, Priorities USA Action, posted its strongest one-month total by raking in $4 million in May.
But the pro-Obama group is still being left in the dust - in part by the latest tally from a Republican super PAC formed by GOP strategist Karl Rove, American Crossroads. It raised $4.6 million in May.
The changing calculus raises the prospect that Obama could become the first incumbent president outspent by his challenger.
