political islam and islamism are word made by non-muslim
the islamic sharia law has economic laws, social laws and political laws
a islamic goverment can be like this the shura council chooses leader who is qualified in islamic studies, he will be leader until he dies or retires, he can not be removed
shura council can be elected by people in country every 4 years and they have to be qualified in islamic studies
it will be democracy because people choose shura council member
but the council will choose leader
