Elected idiot state's accommodated — there's no sense in it (8)
I believe the answer is:
insanity
'there's no sense in it' is the definition.
'elected idiot state's' is the wordplay.
'elected' becomes 'in'.
'idiot state' becomes 'sanity' (I can't explain this - if you can you should believe this answer much more).
'in'+'sanity'='INSANITY'
'accommodated' acts as a link.
I am not very happy about this link. It may be part of another bit of the clue.
(Other definitions for insanity that I've seen before include "Lunacy, derangement" , "Mental derangement" , "folly" , "mania" , "Lunacy, madness" .)
