Internet: French Opinion Polls

Now we know why the French invented the phrase "Je ne sais quoi" (not to be confused with the Swedish band Je Ne Sais Quoi). The opinion polls at Le Monde regularly have 'No Opinion' votes of 6% or higher. Today's question currently has "Sans Opinion" at 9.9%. Let me know if you see an English-speaking poll where that many "Don't Knows" bothered to click on a link.
