Any time she rallies in a town, she makes the local news. Usually it will come with a view of the crowd, maybe a shot of long lines going into the venue, and maybe a brief clip of her saying something interesting/inspirational. She also gets a headshot in the local paper. It also drives discussion about her on social media for the residents. There is a lot of earned media with every rally.
Also, something the campaign is making a point of is contrasting her schedule with Trump's schedule. She is demonstrating that she is younger and has more energy. If Trump tries to match her schedule, he will get even more unstable.
I think interviews with media outlets that have paywalls (NYT, WSJ, WaPo) are practically worthless. If anyone is paying for those services, they already know who they are voting for. Interviews on CNN, NBC, etc. will reach more people, but still have limited value for similar reasons I like that she gave an interview to a local station in Pennsylvania. I think local news is less associated with national politics, and therefore can reach a wider cross-section of a particular city/region. I would like to see more of that.
I don't know much about the podcast stuff. I am old.
