What Would Tightening Look Like?

Nate Silver:

In order to conclude the Electoral College has tightened to the point where the outcome on November 4 is at least moderately uncertain, I would want to see the following between now and the election. Call it the 2/2/2 condition:

John McCain polling within 2 points in 2 or more non-partisan polls (sorry, Strategic Vision) in at least 2 out of the 3 following states: Colorado, Virginia, Pennsylvania.

Not happening yet, at least.
