Which will be easier for Democrats?

Easily the senate. They're already favored to pick up Kirk and Johnson's seats, and all they would need to do is focus on the seats of Ayotte, Portman, Toomey, and Reid.

They've started to give up on Toomey already and there's roughly a 50-50 shot they'll destroy their chances in FL by nominating Grayson. Assuming they keep Reid's seat, they'd need three of NH, OH, The Presidency, IN, NC, MO, and AZ. Not Likely.
