Like past president to blow his top in this state (7)
I believe the answer is:
alabama
'this state' is the definition.
(Alabama is an example)
'like past president to blow his top' is the wordplay.
'like' becomes 'ala' (I've seen this in other clues).
'past president' becomes 'obama' (Barack Obama).
'to blow his top' means to remove the first letter.
'obama' with its first letter taken off is 'bama'.
'ala'+'bama'='ALABAMA'
'in' is the link.
(Other definitions for alabama that I've seen before include "part of US" , "Southern American state" , "Birmingham area" , "State of southeastern US" , "US state west of Georgia" .)
