Which... is ridiculous considering the amount of voters in the country.

Also... polls are typical taken within "people registered to vote, likely to vote..." not people who will vote, can vote, are going to vote.
And then... people lie... people lie when asked their opinions or who they may vote for. People running polls can lie (Hillary was supposed to win wasn't she?)

Polls are stupid, especially if they don't include a choice for corn or blank #2

Interesting, but I remember the question from college.  

How large a sample size is necessary for a population of 300 million, to get a confidence level of 95% that your margin of error is 3%?

And the answer is, 1,068.   Use the sample size calculator above.  

In fact, 1,068 is a large enough sample size for any size population.  I remember the professor showing us this.  

Of course, the trick is to get a random sample, and that's where the real work comes in, but 1,068 is quite sufficient.
