You assume that it needs to be representative. Who says? You? Who are you? You are nobody. You have no credentials.

Since you do not trust me, perhaps you could look at the following links to educate yourself on how polls work.

In data analysis, we use graphs, tables, and numerical summaries to study the variation present in our data. Often, we want to extend our interpretation to a larger group beyond the particular group studied. Such generalizations are only valid, however, if the data we examine are representative of that larger group. If not, our interpretation may misrepresent the larger group

Is a larger sample always better than a smaller sample? All other things being equal, yes, but all other things are rarely equal. A small but representative sample is far better than a large and unrepresentative sample.
