That’s more of a revenge fantasy than a viable political strategy. Of course, you’re not the first person to think of it - in fact, many people have tried this strategy, it’s one of the most common ones in politics. “Attack ads” are an example of it. And they’re effective, to an extent. But they also have a major negative aspect, which is that they reduce the importance of reputation - it becomes an unreliable indicator, because almost every politician’s reputation ends up “destroyed” as you put it. The problem is that people who disagree with you are just as capable of slandering the politicians you agree with as you are for the ones you disagree with. So you end up with a race to the bottom, with accusations becoming more and more hysterical, completely drowning any real signal, and teaching people to ignore it all as noise.
