I guess it makes sense. If they can get another term, they can possibly put Trump behind bars, but it’s not likely to happen before then, if ever since SCOTUS will likely get involved, and the merits of their case is zilch. Until then, they can at least damage his campaign and finances, but leave him viable as the Republican candidate who might be easier to beat.
Kind of risky though. The Democrat party is losing some of its minority base who will either vote for Trump, for a third party or stay home.
Trump is as unelectable as he was in 2016.
