Wavering, abstain -- RIP trying to please both sides? (10)
I believe the answer is:
bipartisan
'trying to please both sides?' is the definition.
'wavering abstain rip' is the wordplay.
'wavering' indicates an anagram.
'abstain'+'rip'='abstainrip'
'abstainrip' is an anagram of 'BIPARTISAN'.
(Other definitions for bipartisan that I've seen before include "using both sides" , "supported by two political parties!" , "Like a coalition government" , "Associated with two parties" , "Supported by both sides - aspirin tab (anag)" .)
