Liberal loves convenience (3)
I believe the answer is:
loo
'convenience' is the definition.
(thesaurus)
'liberal loves' is the wordplay.
'liberal' becomes 'l' (abbreviation).
'loves' becomes 'oo' (**).
'l'+'oo'='LOO'
(Other definitions for loo that I've seen before include "In which one goes" , "Rest room" , "Toilet (informal)" , "Privy" , "A colloquial toilet" .)
