Female Ruler

[Deliverance]

Salam Ladies ,

I am living in a Country where the head of state is a woman,which is a Progress in the strugle for women rights.50 years ago noone could'nt imagine to be ruled by woman,now it is normal only in the islamic countrys it is still impossible for women,to run for elections(except a few countrys).
Many Muslims reject democracy and they have a traditional patriarcally opinion how to rule a state
But in Sura 27:23 you find:
"Lo! I found a woman ruling over them, and she hath been given (abundance) of all things, and hers is a mighty throne. (23)"
And later he(Salomon)corospond with and when she arrived in his kindom,he treated her like a ruler.

How does this square with the mainstream Islam.
