John Delaney has been running for president for almost two years -- he was the first Democrat to announce his campaign way back in 2017.
Here's what he told CNN's Jake Tapper he learned about the experience:
"Well, it's given me an amazing opportunity to listen to people, which is in many ways the most important thing for people who have the privilege to lead our country to do. To hear what's going on in communities, listen to the average American and hear what their concerns are and what's happening in their communities. So not only is it giving me an opportunity to introduce myself to people, Jake, but giving me the opportunity to really listen about what's really happening in our country."
