What's so crazy about comments like this is they have an air of, "we are actually the good guys in the right, but the system works against us!"
You got out-voted.
The numbers suggest that he is not doing what the electorate elected him to do, in general.
(In addition, the Legislature and Executive are designed and intended to be functionally independent, and regardless of the preference the electorate expressed via simple majority, to the extent that independence is threatened by executive action, it's unconstitutional. The President doesn't have a mandate to interfere with that indepdendence for the same reason his election didn't give him a mandate to institute non-carceral slavery).
You can't make statements like "you got out voted" when you actually mean "a few more people from your side turned out and voted, but actually likely the majority of the population doesn't agree with you".
You could argue that apathy is a vote in and of itself, but then you aren't a representative democracy.
