I listened to Vance and Fetterman.
Fetterman has tended to make more sense lately - on Israel, the border, Melendez, standing up to the progressives, etc, but he is so unpolished compared to Vance, it's not even funny. He literally could not answer Rogan's question of "if you could make anything happen, how would you secure the border?".
Rogan let him off the hook too a few times, but it wasn't worth it to press.
