The way it normally does affect USA, Saul (2,5)
I believe the answer is:
as usual
'the way it normally' is the definition.
I can't tell whether this definition defines the answer.
'affect usa saul' is the wordplay.
'affect' indicates anagramming the letters (I've seen 'affected' mean this).
'usa'+'saul'='usasaul'
'usasaul' anagrammed gives 'AS USUAL'.
'does' is the link.
Can you help me to learn more?
(Other definitions for as usual that I've seen before include "in typical fashion" , "Typically" , "'In the normal way (2,5)'" , "In the normal way, habitually" , "In the normal course, routinely" .)
