Does this electoral vote map hold any significance, since it's compiled by an Obama supporter?

All the maps are about the same, and are using projections from current polls. 270towin.com is similar and so is the Zogby map, except they show the lead for Obama. But there are far too many states where the polls are questionable, that this information won't be truly useful as an indicator for at least another three weeks. Once the first Presidential debate is done, the information will be more reliable.
