Reactions inside the House chamber during the State of the Union are highly choreographed

Applause, silence, and coordinated standing—or refusal to stand—are deliberate signals during the State of the Union, used by lawmakers to broadcast allegiance or dissent. At the same time, military leaders and Supreme Court justices largely avoid reacting to preserve institutional neutrality.

The first televised presidential debates of 1960 were seemingly so consequential, candidates opted not to participate in one for 16 years. In the last 60 years, debate format has changed frequently as the political parties and news outlets vie for rules to either protect candidates or increase TV ratings. In this brief video, one expert suggests five interesting innovations to the debate format to make them more informative for the average US voter.
