'get negative response' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.

'urge support' is the wordplay.
'urge' becomes 'push' (pushing is a kind of urging).
'support' becomes 'back' (to back is to support or endorse).
'push'+'back'='PUSHBACK'

'to' is the link.
