We know that Trump is rooting for a debt ceiling meltdown and will do everything in his power to create one. This is partly simple vengeance on Biden and partly the result of his belief that the public will look for a strongman in a time of crisis. But what about DeSantis? What is he going to say?
My guess is that he will mostly stay out of it. If he wants establishment support in the primaries–and he is definitely going to need it–pushing for a catastrophe is not a good way to get it. He will make a few vague statements about the importance of bringing spending under control, and that will be that, unless we fall off the cliff, in which case he will blame Biden.
