Expose Democrat with love for Trump (5)
I believe the answer is:
outdo
'for trump' is the definition.
(synonyms)
'expose democrat with love' is the wordplay.
'expose' becomes 'out' (to out someone is to expose them).
'democrat' becomes 'd'.
'with' is a charade indicator (letters next to each other).
'love' becomes 'o' (love means zero in tennis).
'out'+'d'+'o'='OUTDO'
(Other definitions for outdo that I've seen before include "Surpass, go one better than" , "Surpass - overshadow - excel" , "going to top?" , "Eclipse" , "Perform better than another" .)
