When the six qualifying Democratic candidates take the stage at the CNN presidential debate, there will be several glaring omissions. The cast of Tom Steyer, Elizabeth Warren, Bernie Sanders, Joe Biden, Pete Buttigieg, and Amy Klobuchar will lack some of the field’s most iconic figures, such as Hawaii Rep. Tulsi Gabbard and Andrew Yang. In particular, by not having Gabbard on stage, we’ll be missing quite a lot.

1. This entire debate might go on without anyone pledging to end “failed regime-change wars,” a refrain Gabbard has popularized on the campaign trail thus far. Her saying it in every answer is a bit of a meme at this point, but it’s also of crucial importance. In a time when we have troops engaged in nearly 150 countries and have spent trillions of dollars and lost thousands of lives in failed Middle East wars, it’s a message too crucial to overlook.
