Yes, in Massachusetts.

Head-to-head data just released shows John McCain leading Barack Obama by 3 points — well within the margin of error but still a data point the conventional wisdom might not expect.

A look at the tracking data shows that while the race has often been close, Obama has never held the lead.

Meantime, Hillary Clinton today leads McCain by 5 points — her smallest lead since we began tracking last June, and a significant dip from last month, when she led by 21 points.

Against Rudy Giuliani, Obama holds a two point lead — down from five points when we last polled that pairing, in September.  Clinton leads Giuliani by 14 points today, down from 23 points last month.
