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' (political abbreviation).
'plugs' is an insertion indicator (plug can mean to fill a gap).
'rigged' indicates anagramming the letters.
'election'+'claim'='electionclaim'
'electionclaim' anagrammed gives 'electonicmail'.
'r' placed inside 'electonicmail' is 'ELECTRONIC MAIL'.
'in' acts as a 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?" .)
