Is this grammatical: 彼は映画スターであり、政治家もだ。


I was about to ask a question but I can't without first confirming,

Is this sentence:

[code]

    彼は映画スターであり、政治家もだ。
    
[/code]

grammatically correct, and mean:

[code]

    He is a movie star and also a politician.
    
[/code]

Follow-up question here: [Why does replacing だ to である changes the meaning of a
the sentence?](https://japanese.stackexchange.com/questions/3144/why-does-

Recall that `だ` is the contracted form of `である`.`で` has to be attached to a
noun. You can't leave it behind `も` as `もである`. So the correct way of inserting
`も` will be:

> 彼は政治家でもある

You might be wondering whether `で` before `も` can be omitted. Only arguments
can have the (case) particle omitted before `は` or `も`. In this case, the noun
`政治家` is a predicate, so you cannot omit `で` before `も`.
