That was dumb, but i'm not sure it really constitutes a threat against the president, an insult certainly, but a REAL threat? Bad taste, bad judgement, but a REAL threat, i just don't think so. I can only wonder how many similarly silly polls were started about the Dubya when he was in office.
I think a better poll would've been something along the lines of how many people would like to see the big O die of untreated lung cancer in a socialized medical care system? Not that i am starting that poll or suggesting that the big O should be artificially infected with lung cancer (if such is even possible). That way, people could express their disdain without threatening a crime against a federal office holder.
I hope he lives long enough to get voted out or impeached and thoroughly laughed at, personally.
