Original post by mariachiwomen have always taken part in political decision-making. Check out Cleopatra, Semiramis, Boudica etc or, nearer to us, Catherine the Great, Queen Elizabeth etc
but, if Queens and Empresses did rule, just like Aisha did exert political power, this did not mean that all women were systematically included in the decision-making process. Far from that.
As far as voting is concerned, there were no formal voting arrangements in the Caliphate until the mid-19th century (and then, as an imitation of what some Western countries were doing -and women were of course excluded)
The "shurah" system was an informal consultation system : it did not imply elections, elector lists, constituencies, candidates, majority voting. It was a consultative assembly of elders, tribal/clan chiefs, religious authorities .... what you would expect in a traditional tribal structure
Heavily patriarchal, of course : and, while wives and mothers of potentates may have had some kind of influence in such a system, via their respective husbands, sons etc, or even as widows, the common woman most surely didn't have any
However, if you can produce proof to the contrary, I would be interested in learning about it
