The ballot box is now open.

USA TODAY’s 19th annual Save Our Shows poll asks you to weigh in on which of 26 scripted broadcast series hovering “on the bubble” between renewal and cancellation should survive to see another season.

On this year’s list are two long-running ABC dramas, Castle and perennially endangered Nashville; CSI: Cyber, the lone remnant in the hugely successful 16-year franchise; and, as usual, several freshmen series either too new to judge or with mediocre ratings, including Fox comedies starring Rob Lowe and John Stamos, which have struggled all season, and CBS’s Rush Hour remake, which premiered only last week.

Save Our Shows 2016: The Lists

As more viewers watch on different platforms and traditional TV ratings decline, the calculus that network programmers use to determine which shows stay or go gets more complicated. ABC’s American Crime and Fox’s The Grinder count programming executives among their most passionate fans, but suffer from extremely low ratings. In their favor: Both shows are wholly owned by their networks, so they can benefit from sales to overseas outlets, streaming services and local stations in a way that Nashville and NBC’s The Mysteries of Laura can’t. (That’s partly what doomed ABC’s Forever last year, and will end CBS’s Person of Interest after a shortened fifth season this summer.)

Also unlikely to return are Marvel's Agent Carter (ABC has cast star Hayley Atwell in a promising new-series pilot), an updated version of The Muppets and NBC's Heroes: Reborn. But Fox's The X-Files sequel is on the bubble for a potential 2017-18 return, pending new contracts with stars David Duchovny and Gillian Anderson, and Scream Queens will be back despite weak ratings, thanks to web viewing and the network's loyalty to producer Ryan Murphy. Other freshman series expected back include Quantico, Supergirl, Life in Pieces, Blindspot and Superstore.

CW, jointly owned by CBS and Warner Bros., renewed all 11 of its scripted series, so its only question mark is Containment, a midseason replacement that doesn’t arrive until April 19, and is not included in the poll.

But others’ fates rest partly on how well the pilot episodes turn out for new series vying to replace them.

Series producers often pitch plotlines for new seasons as a way to help ensure their survival; producer Lionsgate has even promised to sign the producers of thirtysomething in a bid to secure a fifth season for Nashville. And some stars take to Twitter to make their case, offering an alternative to pay services that don’t depend on ads, and therefore ratings, for survival. “If you want original, smart/silly comedy to survive on TV you don’t have to pay for, you should tune in,” Grinder star Lowe wrote last week.

Last year, nearly 117,000 fans voted, and among 21 shows in that poll, 10 were renewed, 10 canceled and one, Fox’s The Mindy Project, found a new home on Hulu. Does your ballot count?
