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'm not certain of 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)" .)
