Notice Mike Pence, perhaps, providing guidance (6)
I believe the answer is:
advice
'providing guidance' is the definition.
'advice' can be an answer for 'guidance' (I've seen this before). I am not sure about the 'providing' bit.
'notice mike pence' is the wordplay.
'notice' becomes 'ad' (both can mean an advertisement).
'mike pence' becomes 'vice' (I can't justify this - if you can you should believe this answer much more).
'ad'+'vice'='ADVICE'
'perhaps' is the link.
Can you help me to learn more?
(Other definitions for advice that I've seen before include "Intelligence" , "Formal notice" , "Supposedly wise words" , "Admonition" , "Suggestion (invited or otherwise)" .)
