Eccentric strove with the electorate (6)
I believe the answer is:
voters
'electorate' is the definition.
(I've seen this in another clue)
'eccentric strove' is the wordplay.
'eccentric' indicates anagramming the letters.
'strove' anagrammed gives 'VOTERS'.
'with the' acts as a link.
(Other definitions for voters that I've seen before include "Electors" , "They cast ballots" , "Selectors" .)
