This is the kind of manufactured mystery that's intended to keep the press from asking questions about Republican plans. And it's working! There will be a mystery speaker at tomorrow's convention, in the prime-time spot, just before Marco Rubio and Mitt Romney. Now Gawker is saying that Fox is suggesting it'll be Hologram Ronald Reagan, in the vein of this year's Hologram Tupac performance. I'm sad to say that it's a genuine possibility—everyone has been joking for years that they should just dig up Reagan's corpse and run him again, and this is the next best thing—but there are other options, too. What do you think, Slog?
