I hope I'm wrong about Trump, too, for the sake of the country and of the world; I'm trying to leave a corner of my mind and of my heart open to the possibility that he will prove me wrong.  But we're off to an inauspicious start: the nomination of Sessions suggests that the Trump administration will embark on a full-bore assault on the civil rights (especially the voting rights) of minority communities; and the appointment of Steve Bannon -- a white supremacist and anti-Semite -- is a signal to the hard right, to the alt-right, that Trump will continue to espouse and promote the causes that are dear to them.  The merger of the presidency with the Trump corporate empire and with the Trump family is especially troubling.
As for Republican opposition to Trump: over the course of the 2016 campaign, Republican opposition fluctuated between tepid and impotent, with a huge share of cowardice. In the end, they all caved.  We won't see a new edition of "Profiles in Courage" any time soon.
