Voting system not nice, unfortunately, in US university (9)
I believe the answer is:
princeton
'us university' is the definition.
(I've seen this before)
'voting system not nice unfortunately' is the wordplay.
'voting system' becomes 'pr' (I've seen this in other clues).
'unfortunately' indicates anagramming the letters.
'not'+'nice'='notnice'
'notnice' with letters rearranged gives 'inceton'.
'pr'+'inceton'='PRINCETON'
'in' is the link.
(Other definitions for princeton that I've seen before include "College" , "where War of Independence battle was fought?" , "Early US university" , "Member of the 11 in New Jersey" , "American university" .)
