Deteriorate, as Trump for one might do? (2,2,3)
I believe the answer is:
go to pot
'deteriorate' is the definition.
(I've seen this before)
'trump for one might do?' is the wordplay.
I cannot really understand how this works, but
'trump' could be 'top' (I've seen this in another clue) and 'top' is located in the answer.
'do?' could be 'go' (doing is a kind of going) and 'go' is present in the answer.
The remaining letters 'ot' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'as' is the link.
Can you help me to learn more?
(Other definitions for go to pot that I've seen before include "Deteriorate completely - ready to be cooked?" , "Tea bags will" , "Fall into ruin" , "fail badly" , "Become ruined" .)
