It’s perfectly clear what Don Hill means. It doesn’t take an FBI investigation for a man to recognize a self-righteous prig when he meets one.
Henry Clay famously said he’d rather be right than be President–and ended up being neither. Laura Miller has proven she would rather be right than be Mayor.
If you have not had the experience of being around a person who is right all the time, a good dose of Laura Miller’s company is just the medicine you need. I’d say one or two weeks would be enough for you to understand exactly what Don Hill is talking about.
