[as] stupid as he might be

[Sitifan]

..., unlike what I discovered here in America, any junior high school
student, as stupid as he might be, can precisely discuss the geographical and historical features of all countries in Africa, in addition to any other
country with which Guinea is interacting.

Can I just say "stupid as he might be" instead of "as stupid as he might be"?
