The best cable news show on television is about to get even better. Apparently inspired by the Reason Rally, tomorrow’s episode of Up With Chris Hayes is billed as “an unprecedented look at atheism in America,” and will feature a panel with Richard Dawkins, Jamila Bey, Susan Jacoby, and Steven Pinker. Also appearing will be comedian and Reason Rally speaker Jamie Kilstein, journalist Robert Wright (an agnostic), and “a Christian clergyman [who] will reveal himself as an atheist.”

The show airs live at 8 AM EST on MSNBC, and lasts two hours. The complete episode will be made available online later in the day. They usually start posting segments at about 1:30 PM EST. Up, which premiered last September, gets good ratings, and clips from it are often picked up by blogs and news sites. This is an opportunity for very good visibility, and a step forward for getting atheism into the mainstream of national political discussion. For those who watch the show live and have Twitter accounts, the hashtag #Uppers is used by viewers who tweet about the show while it’s in progress.
