Trying to find a quote about how voting for the good parts of a bill also means voting for the bad parts of a bill

During one of the presidential debates (probably during the primaries) I remember there being an exchange between a long time congressman (maybe Ron Paul or Bernie Sanders) and another candidate about how the long time congressman had voted for or that did some not so good things. Or maybe the long time congressman voted against a bill that did some pretty great stuff but for the sake of making this post simpler I'll just assume it's the former.

This long time congressman justified their vote by saying that although the bill did bad things that he ultimately voted for the bill because of the good things he did, which he proceeded to elaborate upon.

I'd like to find this quote. Like who said it and when.

Any ideas?
