Answer: Tonight can still matter for Haley and DeSantis
I absolutely think Haley or DeSantis can still put together a winning narrative about tonight, based on whichever candidate finishes second. We all expected Trump to win, so there is nothing surprising about it. That will produce ho-hum headlines, whereas the fight for second could be more exciting. Haley could take a second-place finish and go to New Hampshire with positive coverage about that result — and besting DeSantis. Meanwhile, DeSantis could play up a "comeback kid" narrative if he grabs second after Haley seemingly had been the candidate on the upswing. This doesn't mean either has much of a chance of beating Trump for the Republican nomination, but either narrative could extend the race a bit, depending on how voters in the subsequent contests react.
