Obama and Romney are on pace to each raise more than $1 billion with their parties by Election Day.
From the beginning of 2011 through Oct. 17, Mr. Obama and the Democrats raised about $1.06 billion, and Mr. Romney and the Republicans collected $954 million, including some money for the party’s Congressional efforts, setting up 2012 to be the most expensive presidential campaign in history. . .
The overall totals do not include hundreds of millions of dollars being raised and spent by “super PACs” and other outside groups, mostly to benefit Mr. Romney and other Republicans. Groups aligned with Mr. Romney have spent $302 million on campaign advertising that they are required to disclose to the F.E.C., compared with about $120 million for groups aligned with Mr. Obama. Tens of millions of dollars more has been spent on issue advertisements whose precise costs are difficult to measure.
