Loved making a fuss over a communist (6)
I believe the answer is:
adored
'loved' is the definition.
(adoring is a kind of loving)
'a fuss over a communist' is the wordplay.
'a fuss' becomes 'ado' ('ado' can be a synonym of 'fuss').
'over' means one lot of letters go next to another.
'a communist' becomes 'red' (red can informally mean communist).
'ado'+'red'='ADORED'
'making' acts as a link.
(Other definitions for adored that I've seen before include "Worshipped and venerated" , "Loved deeply" , "Loved dearly" , "enjoyed very much" , "Deeply respected" .)
