One question, how is one to know how or what the people want or don't want if you don't ask them? Polling serves that purpose. It's true that a poll, any poll will only tell you what the people want or not want, like or dislike at the time the poll was take. Things change and a week or two or a month or a year, thing can be completely different.
Perhaps there are people who don't want to know what folks think. Just push what that one person wants on all others regardless of what all others think or want?
If one delves deep enough into the polls, they can give you not only numbers but provide reasons to include how and why. But one must go beyond the headlines.
Here's an example poll, taken on 10 March which provides tons of information on a huge range of topics. I find it very useful and informative.
It's high past time that we start electing Americans to congress and the presidency who put America first instead of their political party. For way too long we have been electing Republicans and Democrats who happen to be Americans instead of Americans who happen to be Republicans and Democrats.
