I don't have any strong feelings on the alien vs human characters debate. Even though I am personally only into the humans/humanoids, I really don't mind the others getting content. And some of them I do like for story reasons (Bradley, Garth, Cicero), so I do want to see more scenes with them in general.
But since there has been a lot of debate about this, I was curious about what the poll results actually looked like, though, and here are all of the winners since last spring, when the monthly character polls first started:
So it looks something like this - 5 strictly human winners, 2 Galiano wins (technically human, but modified and transformed), 3 Chip wins (human-looking android), 4 alien wins. Which does kind of seem skewed, but, imo, it looks worse than it actually is.
Chip wins a bunch for novelty reasons, like his customisation options. Riordan and Snake (first time) were voted for so that they would get character art. Also, I think the reason Galiano won the second time in February was because, looking back, it was the first month he could be voted for again after being excluded from all of the polls since July (I assume for story reasons?). I think that might've had an effect on the results, lol.
