To my relief, I have found many example sentences in which the phrase "not so much A as B" is used, but at the same time noticed whenever a noun comes in A or B, it seems always singular, not plural.
If that's the case, could we say the below?
They are not so much a statesman as a politician.
In my gut feeling, I think we could, but cannot explain why.
Would you please tell me if the above sentence is grammatically correct and if so, why that is?
Thank you for your help in advance.
