This is over a month late, but I need to express my admiration and respect for my wife's method of selecting a presidential candidate (and it's not because she's my wife; I literally really like her method).  Just like a product comparison matrix, where different features are compared and weighted to select the most desirable product, a political candidate can be chosen based essentially on a mathematical formula.  I mentioned this in my post about product comparison matrices, but I actually saw it carried out in the recent presidential election.  The benefit of a political comparison matrix is that it takes emotion out of the equation.  Many people vote because they have a "feeling" about someone.  But as any rational person knows, feelings change (especially in reference to political candidates, who often have a habit of changing).  Wendy selected a few specific issues that were important to her, then gathered information about each candidate's position on these issues.  Certain issues had more weight than others, and each candidate's position was given a numerical rank (and not everything is either a 0 or a 1; some issues could have a "totally agree, somewhat agree, neutral, somewhat disagree, totally disagree" type of scale).  At the end, a final number was calculated that summarized each issue, each candidate's position on each issue, and the weight of that issue.  Based on that final number, Wendy made her decision. #politics
