The Art of Elections Forecasting

ideonexus writes "Years ago Nate Silver of FiveThirtyEight.com, a blog seeking to educate the public about elections forecasting, established his model as one of the most accurate in existence, rising from a fairly unknown statistician working in baseball to one of the most respected names in election forecasting. In this article he describes all the factors that go into his predictions. A fascinating overview of the process of modeling a chaotic system."

      To a certain extent, this is true.

      It must be remembered, however, that there are other ways to "advertise".

      The "incumbent advantage" is an obvious one - it's pretty easy to get your name in the news just by proposing a new law, even if you have no intention of following through on it. And the evening news is just more advertising for a candidate.

      Likewise, if a candidate is preferred by the various news organizations, he/she/it tends to get better coverage than a candidate that is actively disliked by the media. Again, free advertising....

      Do remember that it's actually pretty hard to limit campaign spending without tripping over the First Amendment (face it, if a candidate is rich enough, he can just buy a TV station and BECOME part of the media)....

      Correlation != causation.... but only up until you demonstrate the causal connection. The fact that money leads to advertising is self-evident, and the fact that advertising influences opinions and behaviors is also very well established.

      Also, then notion that a vastly more popular candidate will attract vastly more money overlooks human psychology. Other than big donors buying access, why would most donors bother giving money to a shoo-in? What attracts money to a contest (as demonstrated most recently in Wisconsin) is a deeply and relatively-evenly divided electorate.

      I don't believe that is accurate. This suggests that Steve Forbes skipped on matching funds in 1996 and 2000. G. W. Bush skipped on matching funds in 2000 and 2004, which caused Howard Dean and John Kerry to forgo in 2004 as well. Over the last decade, everybody who wins, forgoes matching funds, as well as a significant number of the losers.

      There are valid reasons to say Obama is doing things that are bad, but I think we have a real tendency to say "He's the first to do this!" when he's doing stuff that has been the trend for quite some time.

      Sure, there are laws prohibiting super PACs from coordinating with campaigns, but the candidate can just have his lawyer form the super PAC and the communication between them will be protected by the attorney–client privilege. (for the interest of partisanship I won't name that candidate)

      Certainly the individuals within the corporation are human, and as individuals they are welcome to exert those rights. The corporation is not some sort of composite organism, it is a tool created to focus diffuse stockholder wealth into a more concentrated, versatile structure that can more readily generate profit. To claim it should get human rights is quite akin to claiming that a schoolbus or apartment building should get human rights because they contain humans.

      It's also worth clarifying as an incidental note that a corporation is NOT "made of people" - it employs people, it is controlled by people, but much like a country, it is MADE of the charters, policies, and regulations that define it. Every last person, from the janitor to the CEO can be fired, but the corporation will continue to exist and own it's assets. The stockholders can appoint new officers, new employees can be hired, and operations will resume.

    Perhaps, instead of educating people to understand forecasts, we should be interested in educating people so they can make well informed and educated choices. The great majority of people have little or no education (And I do not mean literacy here). They are unable to analyse, research or investigate in a critical way. They become emotional about things are not possibly capable of understanding and allow those emotions to tell them to whom they should be giving a vote. En educated person, reads between the lines and can see why a candidate is making some promises and can tell which promises will not be fulfilled (Like closing the concentration camp in Guantanamo bay). The only problem, is that politicians that have been elected so far are against the idea of educating people as this will destroy the system as exist today and they will have to get real jobs.

    I don't think it was lies with Obama, I think it was something i consider worse: naivete. Obama came in promising everything to everyone and their mother, because that's what populists do. But when he got into office he realized that he couldn't actually do all that he set out to do, and that Bush's policies in many cases were the best choice of a series of bad options. Case in point: he promised on the campaign trail to close Guantanamo Bay prison, and when he came into office he wrote an Executive Order closing it. It hasn't happened. Turns out that those guys over there really were terrorists captured on the battlefield, and that having them in an isolated location with 3 square and free time was a whole lot better than trying them stateside and keeping them in a SuperMax, especially when no state wanted them in their prisons.

    My biggest problem is not that Obama is a liar, I really don't think he is. I just think he's a moron who sounds intelligent and is a good speaker. He believes in symbols and high ideals that sound great in a speech, like having no lobbyists in his administration, or trying Khalid Shiek Mohammad in New York, getting justice where the crime was committed. Yet when he tries to implement those ideals and symbols, he always seems surprised by the fact that his lofty ideals and symbolism doesn't work in reality, like the cost of the massive security required to host a civilian trial of KSM in New York, the massive protests and unrest, and potential plots to try and free or martyr KSM would come with that, or the fact despite how people hate lobbyists, they're also the best way to communicate to the interests of large segments of the population.
