"Sixty-one percent of Americans said the President should have the
    ability to shut down portions of the Internet in the event of a
    coordinated malicious cyber attack, according to research by Unisys." [1]

While the definition of a kill-switch is broad and may have confused some voters, it is very evident that the hacker community has different (and most likely more informed) views on the issue than the average American. Compared to the 61% of Americans, less than 1% of HN users support the bill (as of when this comment was posted).

Those who consider this poll pointless because they think the idea of a kill-switch is obviously impractical are ignoring the reality. They are being ignorant of the fact that there exists a debate on the topic, even if it seems trivial to themselves.
