...must be "shilling" for the other side.

Nate Silver has a pretty sound methodology with a good track record, about which you have failed to point out any specific flaws. You're the only here just "saying shit".

Apart from that, calling the odds 60/40 in favor of Republicans wouldn't be very effective shilling even if Silver were a shill. For anyone who has any smarts, and was ever motivated enough to go out and work for Democratic victory in the first place, these results are in the useful kick-in-the-pants department, not the instilling hopeless despondency department.
