That can be radically difficult because of gerrymandering.

That aside, launching a public campaign, garnering votes, and voting on a _single issue_ is often the wrong way to elect a representative.

For instance, I think the 2nd amendment is actually a good idea to prevent invasion of a foreign force (an armed population is very hard to rule over). However, I pretty much never vote for candidates that support the 2nd amendment because they often also deny climate change, vote for private prison control, etc. I can't go with their whole platform. I don't want them representing me.

So in those cases, when you have one issue - especially when it's just part of a whole (e.g. just section 1201) - it seems like the right approach, especially when you think there's a piece of legislation (like the Constitution) that supersedes and invalidates the legislation you're looking at.
