Why do the Democrats want Obama assassinated?

There is nothing to be gained, for Republicans and conservatives, from the assassination of Obama.  All that would serve to do is make a martyr for the Democrats and for the left-wing ideas that conservatives honestly disagree with.  It would make the world a worse place.  (I refer to the predictions I have read of Obama's assassination from lefties, and left wing media types reporting of crazed men coming to Obama rallies)

I shouldn't have to be saying what I just said.  Yet, I feel compelled to when I hear of the Lefties talking about it.  They simply assume that there is a right-wing conspiracy to kill Obama because he is black, and that to disagree with Obama is to be dishonest.

I submit that there is a left-wing conspiracy or at least a left-wing desire to have Obama assassinated.  An Obama assassination would a wet-dream and fantasy for every Democrat because it would allow them to do what they really want to do:  be self-righteous and hateful of certain types of Americans who disagree with them.
