If you’re not tired of balloons and bunting, the Democratic National Convention (MSNBC, CSPAN, 8 p.m.; PBS, 8 p.m; CNN, 9 p.m.; ABC, CBS and NBC, 10 p.m.) tries its hand at the political thing in Philadelphia. It ought to have a different tone than last week’s fearfest, with a roster already more full of star power. On night one, that means keynotes by Michelle Obama and Bernie Sanders as well as addresses from vice presidential runners up Elizabeth Warren and Cory Booker, appearances from Sarah Silverman and Eva Longoria and singing from Demi Lovato and Paul Simon. I’d still way the way to go is CSPAN, just to get every speech, musical interlude and procedural flub.
Speaking of choices, Jojo shaves her’s to three on “The Bachelorette” (ABC, 8 p.m.) after TV’s sleaziest event — “fantasy suite” night, this time in Thailand.
It’s the wrong time of year, but good to have a full-length episode of “Murdoch Mysteries: A Very Murdoch Christmas” (Acorn TV, streaming), even if it is online.
If tonight’s “Full Frontal with Samantha Bee” (TBS, 10:30 p.m.) is like last week’s election special, it will involved a long bus ride to the event, and nothing from the convention.
Drew Barrymore and John Hodgkin portray apartment neighbors on “Odd Mom Out” (Bravo, 10 p.m.).
“Rizzoli & Isles” (TNT, 9 p.m.) celebrates its 100th episode.
Bakers on “Cake Wars” (Food Network, 9 p.m.) do a “Beauty and the Beast” design to note the Disney feature’s 25th anniversary. And the voice of Belle, Paige O’Hara, serves as guest judge.
Lena has a 70s-style 40th birthday party on “The Fosters” (Freeform, 8 p.m.).
The top nine dance on “So You Think You Can Dance” (Fox, 8 p.m.), and another is eliminated.
Nobody much liked the turn on last week’s “UnReal” (Lifetime, 10 p.m.), but the show still has to deal with it.
Hollywood actor Robert Franklin, who was in just four movies before he died in a plane crash in 1955 at the age of 25, is featured tonight on Turner Classic Movies in precisely those films: “The Long Gray Line” (8 p.m.), “The Bamboo Prison” (10:30 p.m.), “The Caine Mutiny” (midnight) and “They Rode West” (2:15 a.m.).
Baseball has Detroit at Boston (ESPN, 7 p.m.) and Angels at Kansas City (Fox Sports 1, 8:15).
In Canadian football, it’s Montreal at Toronto (ESPN2, 7:30 p.m.).
