As performance art this poll is a miserable failure. The NY Times led the way in assessing this sort of thing a few years back, when the British film which hinged o the assassination of George Bush was the rage at the Toronto Film Festival. From the Times, with my emphasis:
Oh, geez - the director ducked the tough questions about the possible desirability of whacking Bush and depicted the one pro-assassination character as irrational - how can a Times critic hope to endure?
Well - evidently the tough questions have easy answers now that the President is not Bush. Of course, some of us thought even back in 2006 that this question was pretty easy - killing Presidents is wrong, so don't do it! But we lack the nuance, insight, and global vision of a Times writer or any other typical lefty.
