Vertaling van "often whines and complains about pretty much anything " (Engels → Frans) :

I would like to say to the member opposite that he, himself, often whines and complains about pretty much anything, but when it comes time to vote, he votes in favour.
Je ferais remarquer au député d'en face que, bien souvent, il rouspète et chiale à propos de n'importe quel sujet, mais que lorsque vient le temps de voter, il vote favorablement.
