Sweet to drum out resident, amongst other Republicans (7)
I believe the answer is:
gumdrop
'sweet' is the definition.
(gumdrop is a kind of sweet)
'drum out resident amongst other republicans' is the wordplay.
I cannot really see how this works, but
an anagram of 'drum' is 'umdr' which is located in the answer.
'republicans' could be 'gop' (the Grand Old Party, nickname for US Republicans) and 'gop' is found in the remaining letters.
No letters remain.
This explanation may well be incorrect...
'to' acts as a link.
Can you help me to learn more?
(Other definitions for gumdrop that I've seen before include "Jelly-like sweet" , "Gelatinous type of sweet" , "It may be sucked" , "Small sweet (goody goody!)" , "chew" .)
