It seems they could get away with an “of course we’ll extend them” response and be done with it. It’ll be something that the Republican and Democrat candidate both “agree” on, so it’s won’t be interesting to cover it. Of course, fair to disagree and it wouldn’t be shocking for it to be part of the debate.
My view is that very few people in Congress really care about this ephemeral idea of national debt. They made them temporary because of the Byrd rule; not because they care about the debt. But, I guess we have to wait and see.
