Via the Wall Street Journal:

In the 10 closest Senate races and 40 most-competitive House contests, Republicans raised $60 million in the third quarter, the last public tally of fund-raising before the November elections. Democratic candidates raised $45 million, according to reports filed with the Federal Election Commission over the weekend.
That leaves Democrats in those races with $47 million in the bank, a slight edge over the $43 million that Republicans reported on hand. Nonetheless, the financial momentum for the last two weeks before election appears to be with the GOP.
Republican candidates for the Senate fared best. In seven of the 10 closest Senate races, the Republican candidate raised more than the Democratic opponent. In all, Republicans raised $41 million in those 10 races, nearly $15 more than their Democratic opponents.
The 10 Republican candidates, such as Christine O’Donnell in Delaware, Dino Rossi in Washington and Rep. Mark Kirk in Illinois, now have a combined $25 million in the bank compared with $19.6 million for their opponents.
