It's difficult for a politician to do something that isn't political, so I think we can let them off the hook for making symbolic gestures.
However, putting legislation up for a vote is not puffery. Establishing what parties vote against and why is actually an important part of what the opposition does. Otherwise they may as well not turn up.
Yeah, so, it won't be put up for a vote before the midterms. So? Are you going to vote for the party that at least proposes to do something you want, or will you vote, or leave in place, the party that has proposed nothing or the opposite?
