If you’re a candidate running against an incumbent, I’d focus on what differentiates yourself from that incumbent and really understand.
Let’s say it’s a state legislative position. You’d really want to understand what votes they have taken and how you would have done something differently. A lot of times folks think, “I want to tell you all about what I believe and what my principles are.” But really elected office is a service. It’s a public service position. You should do much more listening than talking and I think people will value that much more than you taking the time to spout off a laundry list of issues that are important to you. I’d encourage those interested in running to really do more listening.
