It’s not a power play. Rogan has the #1 podcast in the world - and he doesn’t ever travel to do his show. Trump, and now JD, are making the investment. The Harris campaign didn’t ask other podcast hosts to come to her.
And it’s worth the investment, even if it took a full day. What’s better, a rally of 5-20k people who are already voting for you, or 30M views on the number one podcast with a simpleton audience (as you guys would probably put it) that could be swayed?
She’s had weeks to make it work. If it doesn’t happen, the Harris campaign never actually wanted it to happen. Which is a mistake IMO.
