The results make sense in the context of the wording of the poll, however, I would wonder if there's really a big difference between "any Alignment" and "typically Evil", and indeed, what people meant by that. It also excludes "always Evil". My experience is that some people will say "any Alignment" when 90% of a race in their game is one moral alignment, and others will say "typically Evil" when actually a large faction of the beings who are non-Evil play a huge role in the campaign.
Personally I barely use Orcs, because they've always had issues in D&D and aren't interesting to me, but I've always made heavy use of Drow and they've pretty much always been of all alignments. Even if the bulk of the society was "Evil" I wouldn't think of the race as "typically Evil".
So I think any awful lot of this is perspective.
