I'm not into conspiracy theories or plots, but there could be some truth in what you post. Two facts. Romney is the GOP establishment candidate and he is the next one in line to be the nominee. Cain endorsing Romney in 2008 is a red flag. Nothing more. After the Florida straw poll last weekend Fox News highlighted Cain at the start of their evening news show on both Sat & Sun and promoted him for several days after wards. And as we all know there are quite a few neocon pundits and newsfolks who work at FNC.
Lots of dots to connect. We'll see.
