Not that I support Fox News or anything (I also only watch it for Tucker), but here's an alternative explanation: Republican voters were watching Fox for their election coverage. When the magnitude of the fraud became clear, they turned that shit off. Meanwhile, Democrats were getting their fix from the MSM, and Biden's victories glued them to the screen.
edit: mind you this is in addition to Fox's recent embrace of leftist narratives.
