Major TV News Networks Agree To Shield Early Exit Poll Data On Election Day

US television networks face a new challenge in covering this year's excruciatingly close presidential election: prevent closely guarded exit poll results from leaking onto Twitter, Facebook and other social media platforms.

The major TV news networks agreed to shield early exit poll data suggesting who is leading in a state until the state's polls close. That means no tweeting exit polls, posting on Facebook, or re-tweeting figures reported by others. Election officials worry that leaks could discourage people from voting if they think the race in their state is already decided, depressing the vote count and distorting the results. In 1985, Congress extracted a promise from the major TV networks to refrain from using exit polls to project a winner in a particular state, or to characterize who is leading, while voting continues in that area.
