Puts in a seat (6)

'puts in a seat' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for elects that I've seen before include "Votes in" , "Appoints via he ballot box" , "Appoints through voting system" , "Selects by ballot" , "Appoints to position in ballot" .)
