The question is how do you know which decade is wrong...

Because google is a search engine it provides relevant information on the topic you need so you get points from both sides on the topic. I think it is a good way to find out more information to decide who to vote for as they don't tell you who to vote for because there is more than one person operating google and they might all have different feelings on the poll.

It is your decision it is there for you to take it
