Existing situation in America? Question coming in to us at broadcast (6,3)
I believe the answer is:
status quo
'existing situation' is the definition.
(I've seen this before)
'america? question coming in to us at broadcast' is the wordplay.
'america?' becomes 'us' (abbreviation for the United States**).
'question' becomes 'q'.
'coming in' is an insertion indicator.
'broadcast' indicates anagramming the letters.
'us'+'q'='usq'
'to'+'us'+'at'='tousat'
'tousat' is an anagram of 'statuo'.
'usq' placed inside 'statuo' is 'STATUS QUO'.
'in' is the link.
(Other definitions for status quo that I've seen before include "Existing state of affairs; rock group" , "Existing position" , "The current situation" , "Unaltered state" , "Current state of affairs" .)
