When it comes to Nate Silver’s political analysis I think he tends to be pretty balanced since he runs it all on numbers. But to the degree that he does have a bias it would be for, not against the Democrats.
With that in mind his review of the NY-9 and NV-2 elections do not bode well for the Democrats in 2012.
Personally I still expect the most likely outcome for January 2013 to be President Obama in the White House but Speaker Boehner and Majority Leader McConnell at the other end of the avenue.
