Most Breitbart trutherism springs from one source -- Breitbart's speech at CPAC last month, in which he claimed ownership of anti-Obama dynamite. "We've got videos," said Breitbart. "This election, we're going to vet him -- from his college days." The theory, summed up neatly by video titles like "ILLUMINATI ASSASSINATION?," is that the Obama regime took out a critic before he could unleash damaging material.
