Party's full of large Liberal dummies! (5)
I believe the answer is:
dolls
'dummies' is the definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Maybe there's a link between them I don't understand?
'party's full of large liberal' is the wordplay.
'party's' becomes 'do's' (do is a kind of party).
'full of' is an insertion indicator.
'large' becomes 'L' (eg in clothes sizes).
'liberal' becomes 'l' (abbreviation).
'l'+'l'='ll'
'dos' enclosing 'll' is 'DOLLS'.
Can you help me to learn more?
(Other definitions for dolls that I've seen before include "Guys and ---, musical" , "Small replicas of people" , "Child's playthings" , "Play figures" , "Police speed-measuring zone" .)
