1) “Empire” return, 9 p.m., Fox. For six seasons, “Empire” has had an odd mix – great music and messy, over-the top soap opera. For this final season, it aired 10 episodes, then took an 11-week break; now it’s back for its last 10. Fox says only that there’s a “shocking revelation” tonight; there usually is. It implies that a death shakes the Lyon family; also, Andre (Trai Byers, shown here, center) makes an important decision.
2) Election coverage. The presidential race has been big this year, with the wo recent debates drawing record ratings. Now the networks are shoving most of their entertainment shows aside for “Super Tuesday,” when 14 states decide one-third of the Democratic convention votes. ABC starts at 8 p.m. ET, CBS and NBC at 9 and the news channels go all day. Bernie Sanders had been on a winning streak until Saturday, when Joe Biden got almost half the South Carolina votes, more than doubling Sanders.
3) “The Resident,” 8 p.m., Fox. There are some great personal moments at the beginning and end of this hour. In between? The hospital’s ready to get out of the childbirth business … the doctors deal with two bizarre cases … and a going-to-the-dance story seems to have an elastic timeline.
4) “The Flash” and “Legends of Tomorrow,” 8 and 9 p.m., CW. With three big networks covering the primaries, the others get a big chunk of the entertainment audience. Fox has new shows, but CW settles for reruns: “Flash” has its Valentine episode, with Amunet (Katee Sackoff of “Battlestar Galactica”) intervening; “Legends” has its season-opener, a light episode with a documentary crew onboard.
5) More, cable. “Schitt’s Creek” (9 p.m., Pop) has an OK episode , concluding with the town’s very funny travel video Or you might spend election night watching a Leonardo DiCaprio film – “The Aviator” (2004), at 6:08 p.m. on Starz, or “The Wolf of Wall Street” (2013) at 7 on FX. Other movies include “Back to the Future” and its sequel (1985, 1989) at 6 and 8:30 p.m. on Freeform and the early career of Ruth Bader Ginsburg in the excellent “On the Basis of Sex” (2018), at 9 on Showtime.
