Compromise happens when you hold firm on a position and never yield no matter what the pressure, and the other side comes begging for you to make a deal. Repeatedly declaring to your opponents that you have no principles and just want to make a grand bargain for the sake of optics is exactly why the left is in the sorry state that it's in these days. Centrists seem to think that you can just throw away every bit of leverage you have and that somehow the right wingers will still be willing to come to the table, despite all the evidence to the contrary over the last 40 years.
