Potentially- but again, the left didn't really think or talk about the Epstein files during the Biden admin. It was a non story politically other than conspiracy theorists in the corners of the internet clamoring for them, until Trump made it a part of his campaign.It's possible that dems thought some of their own would be implicated. Reps might be thinking the same thing about their side.
That said it seems highly unlikely that the dem DOJ had the goods on Trump but decided not to shift the focus of their campaign.
