Either this poll is wrong by at least 6 points, or, The Democrats have just lost both the House and Senate. At a 15 point differential between Reps and Dems in likely voters an 8 or 9 point wave factor in favor of the Republicans is inevitable. With that I see 78 Rep seats in the house and 11 or possibly 12 in the senate giving the Reps control there also. As an example Sharon Angle should beat Harry Reid by 10 to 11 %. Boxer in Ca should loose by 5 to 6 points. And if you factor in the margin of error O'Donnell could be within striking distance of Coons.
