I think it’s time for Dems to worry.

My latest double-calculator poll calculations show a significant tightening in 4 out of 5 calculator numbers:

1. 5
2. 6
3. 9
4. 2
5. 3

How does Obama pull it off in the face of such numbers?

In the immortal words of Mad Skillz, this race is now “tighter than five virgins in a Volkswagen.”
