I'd just like people to not base their votes on possible "existing" issues, alright.
Who cares if you have problems envisioning an Electric / Poison Pokemon...we can make something up.
We are a creative community, we have it in us to come up with something acceptable for any type combination, lol.
That said, I don't really like Poison / Electric at all due to what I am fearing as a limiting effect.
Remember, in the submission accepted for the concept, Wish, Encore, Gravity, Trick Room, Tailwind and the like were emphasized, while the common utility moves like Toxic Spikes, Thunder Wave and the Screens were accepted but preferred as non priorities. With Poison AND Electric, I am afraid we will take our limited move slots and fill them with non exciting utility moves.
Poison / Dragon offers a much more useful set of resistances first of all, but also the Dragon typing and its "mystic" aura allows for us to emphasize a much more varied set of utility moves than Electric would offer us.
That said, Sunday please note in my original post that I have changed my vote. Dragon is now first, and Steel is now second. Thank you.
