Today's daily tracking poll from Gallup shows a 10-point edge for Barack Obama over Hillary Clinton, similar to what is has been for nearly a week. It looks like a stable margin but I noticed within the gap a trend emerging: an inrease in Democrats answering "other" or "no opinion." Here is what it looks like:

The changes day to day are small and could be interpreted as statistical noise but the steady trend makes me think otherwise. Could it be that some voters are rethinking their decision? If so, the steadiness of Obama's numbers (around 50 percent recently) and decline of Clinton's (now at 40%) would suggest that some of her supporters are having doubts. And it's not just average voters showing signs of waffling. Some former Clinton backers seem to be waffling as well.
