Crazy Democratic fool in days long past (2,3)
I believe the answer is:
of old
'in days long past' is the definition.
'crazy democratic fool' is the wordplay.
'crazy' indicates an anagram.
'democratic' becomes 'd' (political abbreviation).
'd'+'fool'='dfool'
'dfool' anagrammed gives 'OF OLD'.
(Other definitions for of old that I've seen before include "at one time?" , "In or from former times" , "Formerly" , "Long ago" , "these days? No!" .)
