interregnum

His current place in history is as the Democratic interregnum between the two Trump presidential terms.

In all, President Biden’s time in the White House will, in the mid to far future, likely be looked back upon as some interregnum and intervening years in the larger Trumpocene.

Then there is the post-presidency - or, in Trump's case, a presidential interregnum.

In Trump’s between-terms interregnum, he and Putin seemingly stayed in touch, with at least seven phone conversations that took place outside the purview of U.S. diplomacy, according to journalist and author Bob Woodward.

You can't blame voters for getting a little overheated in their rhetoric during the election season and moving on with their lives in the interregnum.
