A loyal following always with me, too (3,4,7)
I believe the answer is:
for good measure
'a loyal' is the definition.
I can't judge whether this definition defines the answer.
'always with me too' is the wordplay.
'always' becomes 'for good' (for good can mean permanently or forever).
'with' is a charade indicator (letters next to each other).
'me too' becomes 'measure' (I can't justify this - if you can you should give a lot more credence to this answer).
'forgood'+'measure'='FOR GOOD MEASURE'
'following' is the link.
Can you help me to learn more?
(Other definitions for for good measure that I've seen before include "as finishing touch?" , "Why we calibrate scales" , "in addition?" , "as well" , "as an extra precaution" .)
