How a poll works.

I did this little survey poll on favorite cookies. To keep it simple, there were 2 families, both with 5 kids, called the Blue family and the Red family. The blue family voted like this: 

Peanut butter -- 1

Chocolate chip -- 1

Oatmeal -- 1

Ginger -- 1

Oreos -- 1

Sugar -- 0

The red family had never tried any other kind of cookie but sugar, and so voted like this:

Peanut butter -- 0

Chocolate chip -- 0

Oatmeal -- 0

Ginger -- 0

Oreos -- 0

Sugar -- 5

So the total results were:

Peanut butter -- 1

Chocolate chip -- 1

Oatmeal -- 1

Ginger -- 1

Oreos -- 1

Sugar -- 5

Well it is obvious! Sugar cookies win!

Now substitute the names

Jimmy Carter -- 1

Bill Clinton -- 1

JFK -- 1

LBJ -- 1

Obama -- 1

Reagan -- 5

And that my friends, is how polls are skewed.
