The last afternoon of panels is stacked, and three of our best have been scheduled at the same time, so FDL will attempt the unprecedented, unscripted and extremely dangerous triple liveblog!

Over on Emptywheel, Rayne will be covering Marcy as she takes on one of Obama’s signature broken promises: the failure to close the detention center at Guantanamo Bay. On our Elections page, Michael Whitney will liveblog a panel on marijuana policy and politics featuring Jon Walker. And at the FDL News Desk, my fingers will do their level best to keep up with David Dayen as he tackles the foreclosure crisis.

A bit of good news coming out of Arizona, despite the state’s disaster of immigration policy. Medical marijuana advocates in Arizona announced today that they qualified for a spot on this year’s ballot after turning in about 252,000 signatures, well more than the 145,000 required by the state. That means when Arizonans hit the polls this November, they’ll be able to vote to allow medical marijuana use in the state.
