And once again - TIA uses not a Monte Carlo simulation to prove his point, but the Martingale betting strategy.
Implausible 2008 returning voters and 2012 vote shares
Obama had a 56.2% recorded share in Wisconsin and 63.3% in the unadjusted exit poll (2.4% margin of error). Assuming Obama had a 60% True Vote share, then to match the recall vote, Walker needed the following:
1) 81% of McCain and 71% of Obama voters turned out.
2) He needed to win 25% of Obama and 95% of McCain voters.
3) He needed 46% of new voters who did not vote in 2010. The 2012 exit poll indicates he had 45% and that new voters comprised 13% of the total vote.
In order to win by his recorded vote, Walker needed a 10% advantage in returning 2008 voters and a 20% advantage in net defections. That is highly implausible.
To explain my comparison to Martingale betting : Most people know it by the phrase 'Always bet on black' - what the gambler does is place a bet on black in roulette. If they lose, they bet double on black, if they lose again they double that bet, etc etc etc. until they win, then they start again. People believe that 'Red can only come up so many times, then it has to be black' and they ask questions like 'what are the odds of it coming up red fourteen times in a row ? a billion to one ?' - Here is the thing -The Martingale system is a fallacy. As every spin of the roulette wheel is unique, the odds of the ball landing on black are exactly the same every time. (just slightly less than 50/50 - don't forget that '0' is a green space.)
In the case of a voter, the odds of them voting this way or that are also unique to that voter, yet TIA insists on using a Martingale strategy to predict a voting pattern which is wrong, wrong, wrong. He swears that voters are less like a roulette wheel, and more like a deck of cards. (Monte Carlo simulation) With a deck of cards, there is a defined box of probability. If I shuffle a deck, the odds of me pulling out an ace of spaces is 1 in 52, if I fail the odds of me pulling out the ace becomes 1 in 51, The odds of the next card picked being correct increases with every incorrect pick beforehand. Look at TIA's 'proof' above - he is making the assumption that past 'decks' of votes contain the same 'cards' that current decks contain. In short - Charnin is card counting. Wrongo. Each deck consists of one voter. The odds of them voting this way or that is determined in part by the choices on the ballot before them. Anyway, the proof of Charnin's fallacy is found in the casinos themselves. Casinos don't ban Martingale betters, because they almost always leave empty handed. Card counters however are lucky to leave alive.
