I don’t like Obama any better than you do, but this shouldn’t get a pass. Would you have felt the same way if it had been Sarah Palin, Herman Cain, etc?
Your question is well founded. I’m sure there would be a lot of hypocrites on something like this.
But I can can honestly say yes, I would feel the same way if this situation happened to a President that I liked. I wouldn’t take a graphic from a state party as a serious assassination threat. There are many online games that involve doing harm to or killing poorly rendered graphical representations of Obama, Bush, and other Presidents and Presidential candidates. I doubt the secret service investigated them all and they are legal under the first amendment as is this ill-advised graphic of zombie Obama.
I’m sure there are enough real threats made against the President to occupy the secret service’s time.
