Leftist with a cold in shot (5)
I believe the answer is:
raced
'shot' is the definition.
(I've seen this in another clue)
'leftist with a cold' is the wordplay.
'leftist' becomes 'red' (red can informally mean communist).
'with' indicates putting letters inside.
'cold' becomes 'c' (eg on taps).
'a'+'c'='ac'
'red' going around 'ac' is 'RACED'.
'in' acts as a link.
(Other definitions for raced that I've seen before include "went at speed" , "Went fast" , "Hurried" , "bolted" , "Ran fast" .)
