Blazing about Republican, OK? (7)
I believe the answer is:
alright
'ok?' is the definition.
('alright' can be a synonym of 'ok')
'blazing about republican' is the wordplay.
'blazing' becomes 'alight' ('alight' can be a synonym of 'blazing').
'about' indicates putting letters inside.
'republican' becomes 'r' (abbreviation).
'alight' going around 'r' is 'ALRIGHT'.
(Other definitions for alright that I've seen before include "very well, as some would put it" , "Satisfactory or adequate" , "Okay" , "uninjured" , "Fine; agreed" .)
