The second collaboration will prominently feature voices from The Washington Post that will contextualize and dissect the political debate as it unfolds.

Genius, the online annotation platform that empowers users to annotate any page on the Internet, will reunite with The Washington Post to annotate tonight’s second Republican presidential debate in Simi Valley, California. The first Republican presidential debate in August marked an unprecedented usage of Genius annotation technology by a major national news outlet to provide in-line commentary on a live political debate transcript and shape a comprehensive news experience.

Washington Post journalists Chris Cillizza, Philip Bump, Janell Ross, Amber Phillips and Michelle Lee will be annotating the transcript as soon as it becomes available here, overlaying the text with another dimension of conversation and sharing their expertise, insights, and reactions.

Readers can follow the discussion by clicking the highlighted lines on the page. Anyone who wishes to join the discussion — including presidential campaign staffers — can simply highlight text on the page, follow the prompts to create a Genius account, and begin writing annotations.
