4.6 million people in a poll? That's a HUGE number. Note that the EU parliament actually did pass a law to abolish changing the clocks, but I think it didn't pass the other branches of EU government, so probably got lost. Hopefully it can be revived in future. The accuracy of a sample, as long as it's representative, doesn't depend that much on the population size, just on the size of the sample. Once you get past a few thousand samples you are accurate to a couple of percent no matter how big the population is. The question here is was the poll representative? That depends on how those 4.6 million people were selected.
