You do realize that Bob was a lot different then his family? Have you ever read anything about him? Or do you think because he smoked herb that he must vote Demo? As a Rastafarian he didn't agree with homosexuality and also didn't agree with abortion.
It is interesting to see how the brain sees what it wants to see. It is too bad that good folks like Bob Marley cannot be untouched my their own parties political propaganda.
On another note, just because someone takes a picture at the Whitehouse with the POTUS and the FLOTUS doesn't mean they agree with their party platform. If I was offered a chance to go and take a picture with them I would, but that wouldn't change my belief structure.
