I never watch the guy. Nothing against him, just too busy. But I see at least 37 million watched his 3-hour Trump conversation. Trump seemed to enjoy it - but Trump likes to interact with people. Rogan is not a Trump fan, by the way, but he is civil. He sure is popular.

Who knows whether her appearance on Rogan would help or hurt her prospects?
