Were those polls, like the poll he once did for the condtional expression?
There the poll indicated no specific proposal had a majority, so for each
specific proposal one could say it didn't have popular support, but the
majority still prefered to have a conditional expression. But at that
time Guido used that poll as an indication there was not enough support.

So colour me a bit sceptical when Guido comes with such a poll.
