If you came out of the polls, and saw some freak with a neck tattoo and a ring in his nose,
carrying a clipboard, would you walk toward him, or the other direction?
This is the one tidbit they really don't understand or refuse to accept. Exit polling relies on voluntary participation, and the demeanor & appearance of the pollster can sway who is willing to participate.
If the pollster has a goatee, multiple piercings & many visible tattoos - he will attract a different segment of responders than someone dressed in a suit & tie, and wearing an American flag lapel pin.

**Friends of TIA - or TIA himself.....
What you do is wrong for the same reason the 'Martingale Strategy' is wrong.
(The Martingale strategy usually appears in Roulette where one always 'bets on black' and doubles down until they win, then the person goes back to the minimum bet and continues to double down until they win again - the doubling allows your theoretical 'win' to cover your previous losses, if you Martingale at about 250% the theory is you will cover your losses and make a tidy profit.. ) -- Just like every spin of the roulette wheel is unique, every person is their own dataset..
In the case of Martingale betting, the player assumes that 'the odds are black has to come up soon because its been red too many times in a row' is a false assumption. Since each wheel spin is unique the odds never change - each spin is its own dataset - like people are. Because I get out of bed on the left side today, doesn't change the odds that I will get out of bed on the right side tomorrow. The same is true when talking to exit pollsters.
Now, when you take a bunch of unique datasets and then Monte Carlo them like TIA, you are essentially running a Martingale strategy, insisting that if so many people voted for X, then a smaller sample will show the same percentage of people also voted for X. -- Wronggidy-wrongiddy, wrong-o.
BTW - If you do decide to use the Martingale the next time you play roulette, just remember this...Casinos allow you to do this because eventually you will lose everything if you don't stop. And most players don't, they play until they run out of money, or realize they can't cover their own bets anymore and pull out with less than they started with.
