Compromising and using empathy to understand the opposition's views so that you can negotiate for what you need does not satisfy the base, and does not satisfy social media. The (naive) game theory of negotiation says that it is better to stake out an extreme position so that you get more of what you want when you negotiate it away. And the dynamic of primary elections also allows traitors or traders to be punished if they defy the desires of the party too much.
