Republican plugs rigged election claim in post online (10,4)
I believe the answer is:
electronic mail
'post online' is the definition.
I can't tell whether this defines the answer.
'republican plugs rigged election claim' is the wordplay.
'republican' becomes 'R' (abbreviation).
'plugs' indicates putting letters inside (plug can mean to fill a gap).
'rigged' indicates anagramming the letters.
'election'+'claim'='electionclaim'
'electionclaim' with letters rearranged gives 'electonicmail'.
'r' inserted into 'electonicmail' is 'ELECTRONIC MAIL'.
'in' is the link.
Can you help me to learn more?
(Other definitions for electronic mail that I've seen before include "Form of communication" , "message on screen?" .)
