Here's another fun stat that reveals just how badly the GOP is getting financially outgunned by the Dems in the battle for the House -- and how much of a hard time they'll likely have in trying to hold on to even their current number of seats.

A review of finance reports by CQ found that of the top ten best-funded candidates who are challenging incumbents, nine of them are Democrats. Among the very well-financed Dems are Jim Himes of Connecticut, Darcy Burner of Washington state, and Dan Seals of Illinois.

It gets better. The one Republican candidate on the list, businessman Sandy Treadwell of New York, is a self-financier. In other words, GOP donors didn't put a single challenger on the top-ten list.
