Lets say there are 10 polling firms polling on any given night..

10 x (about) 4000 per poll = 40,000 people.

There are 280,000,000 citizens in the USA

40,000/280,000,000 means on any given night you have a 1 in 7,000 chance of being called. -

You will get called roughly once every 20 years or so...

It's like the lottery, except there is no prize :D

You cannot get on a list to be called (at least not for "scientific" polls)  The key, unbreakable rule in polling is that the sample cannot be self selected ie you have to be randomly picked, and cannot volunteer.

This is why internet polls are useless - the people who vote choose, or not, to participate.

Oh I wish I could get a call. I am on the Do Not Call registry does that affect things?

The "Do Not Call" law specifically exempts public opinion research, and other political activities, such as campaign calls, get out the vote, etc...

Hey, politicians lived and die by polls - of course they have been exempted by the law!
