These are the same laws that define the likelihood you will win any game of chance such as a lottery or raffle. That means that if Gallup conducted the same poll times at the same exact time the result to any question on that survey would come within four percentage points of the "true" figure in 95 of those surveys. A classic demonstration of this involves setting up a bowl with an equal number of well-mixed red and blue marbles -- say 1, each.
If you reach in and blindly and select marbles, you are highly likely to get close to 50 marbles of each color. If you do the same experiment times and plot the number of blue marbles you get each time on a graph, the resulting pattern will be a bell-shaped curve with the "correct" answer of 50 being the most common result. When Gallup conducts its national telephone polls, picture the company's telephone interviewing centers reaching out and randomly selecting households in the same way.
There is a lot more complexity to America than red and blue marbles; Gallup is reaching into a "bowl" of numbers representing a vast variety of people and attitudes.
