Ok, sorry, but ATTACKED!!!! is probably a little strong.

Lets try vandalized next time.

Attacked is the right word. The office is a legitimate place of business with election signs in the window. Throwing rocks and shooting up the windows sounds like 'attack' to me.

Unless one is speaking metaphorically; only animate objects can be "attacked".

An office cannot be attacked.
