Democrats in race, worn down, offering compromise position (6,6)
I believe the answer is:
middle ground
'compromise position' is the definition.
(area two sides can compromise on)
'democrats in race worn down' is the wordplay.
'democrats' becomes 'DD' (two abbreviations for Democrat).
'in' indicates putting letters inside.
'race' becomes 'mile'.
'worn down' becomes 'ground' (ground down).
'dd' inserted into 'mile' is 'middle'.
'middle'+'ground'='MIDDLE GROUND'
'offering' acts as a link.
(Other definitions for middle ground that I've seen before include "Area for compromise between two positions" , "Compromise position" .)
