Write about Liberal in shock (4)
I believe the answer is:
jolt
'in shock' is the definition.
(I've seen this before)
'write about liberal' is the wordplay.
'write' becomes 'jot' (jotting is a kind of writing).
'about' means one lot of letters goes inside another.
'liberal' becomes 'l' (abbreviation).
'jot' going around 'l' is 'JOLT'.
(Other definitions for jolt that I've seen before include "A sudden jar" , "bump" , "Sudden impact" , "Sudden shock" , "elbow" .)
