It’s a tactic that is used both ways.
If I want something and you want my vote, you can put what I want in your bill. So I can vote for my thing and yours at the same time. It would force me to vote yes on something I might otherwise vote no on a piece of it.
If I *don’t* want something, you can put it in a bill with something else I want. It would force me to vote no on the package even though I would vote yes on a piece.
Where that line is depends on the person and the situation. Knowing where the line is with other people is the basis of politics.
