Suspend Republican dealer (6)
I believe the answer is:
draper
'dealer' is the definition.
(I know that draper is a type of dealer)
'suspend republican' is the wordplay.
'suspend' becomes 'drape'.
'republican' becomes 'R' (abbreviation in US politics).
'drape'+'r'='DRAPER'
(Other definitions for draper that I've seen before include "Cloth merchant" , "Retailer of cloth" , "man of the cloth" , "Seller of textiles" , "Dealer in cloth and clothing" .)
