A selective critical checklist of notable Tuesday TV:

Democratic Presidential Debates (8/7c, CNN): With a field still so big the debates are split between two nights (the remainder appearing Wednesday), 20 primary contenders will appear for a second round of Qs and As on the stage of Detroit's Fox Theatre, with CNN's Don Lemon, Dana Bash and Jake Tapper moderating. The first night's headliners include Elizabeth Warren, Bernie Sanders, Pete Buttigieg, Beto O'Rourke, Amy Klobuchar — and for comic (or possibly spiritual) relief, Marianne Williamson among too many others. Seriously, people, get a grip, or a reality check, and cull this herd.
