Except that in my experience, even a supporter of said party, when talking about how a member of ours "just toes the line" is communicating a negative, not a positive. That's not a good, genuine guy we're proud of, it's someone to watch out for.
Colloquially too, the way I was raised, it's a bad thing, you did not want to be a line-toer. And I'm not referring to discussions of politics, but how it was used in day to day conversation. I've been accused of toeing lines, for instance, with the implication being that continuing may get me in trouble some day and I should be a little more careful.
Perhaps it's a regional thing.
They used local guides, who knew the routes, dangers and resources they might encounter.
