JASON RILEY (GUEST): I'll take Joe Biden at his word that he is interested in unity. But I think the left in general, I don't think is interested in unity, I think they're interested in revenge, Bret. And you know, when you want to set up a blacklist of former Trump administration officials and make it harder for them to get hired going forward, that's not about unity, that's about revenge. Or when you embrace an agenda of a critical race theory or diversity training or The 1619 Project or calling out white people and publicly embarrassing them, that's not about unity, that's about revenge. And I think that right now is what is animating the left more broadly, regardless of what Joe Biden is saying.
