I know about the public.
A few years back, I was working on a high-profile issue. I can't go into the details, but imagine it was a battle between X and Y, and Y is the status quo.
I happened to personally want X, but I was hired by Y. Here's the thing- I knew that, as a matter of law, X was going to fail.* Miserably. But I knew a lot of people that were really in favor of X. And were giving a lot of money to X. And there were a lot of passionate feelings about X. But it was always going to be a boondoggle, because it could never happen.
I can still recall trying to explain this to some close friends, and while some of them who knew me well (and my areas of expertise) wisely chose not to donate to X, others ... well, it was money not well spent. And a lot of people are still really angry about it that I know. Angry that they spent all that money, and angry that the thing they supported ... didn't happen, and they still can't quite understand why (because law is hard, especially when you have a vested interest in not understanding it).
*To give you an idea; imagine someone in your town wanted to get rid of the federal income tax. So they had the town pass a law saying that the people in the town ... don't have to pay federal income taxes! Great idea, right! And, of course, you're going to get a lot of people really excited about it. And you're going to be able to say, "BUT THE VOTERS SPOKE!" Trouble is ... that's never going to actually happen. Basically, that's what occurred. People were promised something that couldn't happen. Still makes me angry thinking about it to this day.
