On the stump for Barack Obama yesterday, Hillary Clinton warned Democratic supporters not to get too "overconfident" with polls showing Obama leading by double digits over John McCain. Why not? Well, by this morning, new polls had that lead down to 4 percent.
That's the way it goes in tight election years - everything we know for certain is likely to change several times before November 4. With the only real poll being the one at the end...in the voting booth.
