"Your math is indeed bullshit," writes commenter Jeffrey McManus about yesterday's Zogby poll result that gave John McCain a 5 percent lead over Zogby's usual front-runner, Barack Obama. "The presidential election is chosen by electoral votes selected on a state-by-state basis. Any poll that tries to dumb down the situation by displaying a straight percentage of voters is bullshit." Let me shorten that: "Any poll ... is bullshit." Including the aspiring experts at the poll rollup site McManus recommends, Electoral-vote.com.They called it for Kerry in 2004, by refining a guesswork algorithm until it forecast the electoral vote count almost exactly backwards. The site's editor seems to believe that applying the right mathematical formula to inaccurate poll results will get him accurate results. That's the epitome of the old programmer's saying — Garbage in, garbage out.
