I see each Democrat winning (5)
I believe the answer is:
ahead
'winning' is the definition.
(both can mean in the lead)
'i see each democrat' is the wordplay.
'i see' becomes 'ah' (exclamation used to indicate understanding).
'each' becomes 'ea' (abbreviation).
'democrat' becomes 'd'.
'ah'+'ea'+'d'='AHEAD'
(Other definitions for ahead that I've seen before include "Forwards" , "advanced" , "In the vanguard" , "What's down the road" , "In front as in race" .)
