Im not convinced either way on these charges. Cosby could be guilty of abusing his position and raping women/girls because he knew he could get away with it. He could also be the target of character assassination for criticizing the Black leaders and Obama for failing to take personal responsibility. I take the charges far less seriously because of the long delay between the alleged events and the public claims, but I dont have a strong impression either way on what the truth might be.
There is no conspiracy against Cosby by Democrats.
