ELECTION SETBesides helping set the direction for the country, your vote today will be counted on in the myriad of election result programming planned tonight.

While in the past midterms generally only got an hour of prime time coverage, if that, all three networks are going wall to wall tonight with three hours of returns and reporting.  “Campaign 2018” (CBS, 8 p.m.) is helmed by Norah O’Donnell, Jeff Glor and Gayle King; “The Vote: America’s Future” (NBC, 8 p.m.) has Lester Holt, Savannah Guthrie and Chuck Todd. And “2018 Midterm Election” (ABC, 8 p.m.), will be anchored by George Stephanopoulos, David Mure and Martha Raddatz. In addition, NBC is already pre-empting “The Tonight Show starring Jimmy Fallon” to report late returns into the wee hours.

“NewsHour Election Night Coverage 2018” (PBS, 8 p.m., check local listings), with Judy Woodruff, David Shields and David Brooks, is going straight to midnight — with no commercials. Of course, there will be constant coverage on cable news network, with dedicated results shows starting as early as 5 p.m. on CNN with Wolf Blitzer, Jake Tapper and John King at the big board. At 6 p.m. on Fox News, it’s Bret Baier and Martha MacCallum, with Bill Hemmer at its big board. Rachel Maddow and Brian Williams anchor the coverage on MSNBC at 6 with the over-caffeinated Steve Kornacki at his big board. CSPAN coverage begins at 8 p.m.
