The reason that elections are decided on fringe issues while the central ones get ignored, is actually rather interesting. I believe I read it in A Mathematicial Reads the Newspaper.
The thing is that there exist a great deal of very important centrist issues. However, people do not feel very strongly about them, and they will not base their choice of president on any particular one.
There also exist fringe issues about which most people might feel passionate about, but about which some may feel so passionately about that they become one-issue voters.
Lastly, you combine the above two with the fact that people do not ponder deeply enough their choice of president. Thus, what you would expect that the non-passionate issues would still in the end add up and compete on their true value doesn’t actually happen. If it did, then everything would make sense. Some things a few people care a lot about, others a lot of people care somewhat about. However, people do not think carefully enough to tally up those subtle issues properly.
What ends up happening is that it makes much more strategic sense to focus on the few fringe issues that matter a lot for some people, than to focus on the many centrist issues that matter for a large number.
Sigh, that’s why our democracy is messed up. At least, we have to give people a few days off, sit them into rooms, and force them to study things carefully before they vote. Of course this brings up many questions about who determines the reading material and how do you monitor whether people read it (ie who decides the quiz questions). One strategy is to have voting on that too, and to have voting on whether that previous round of voting was objective, and to have voting on the round of voting just mentioned, ad nauseum. It sounds impractical, but actually technology has just matured to take it into the realm of possibility. (And anyone, particularly with Flash experience, who wants to join me in the task of putting such a scheme together, is powerfully besseched to do so.)
But anyway, competition (though it sorely lacks now) is the most important thing in regard to nearly anything. Unity will only kill competition, create one-party rule, etc.
Second, who exactly determines which party gets the presidency and which gets the VP? Unity should really think about some other scheme, such as a multi-person panel, which will share the presidency itself. If it can figure this out well, it’ll actually have a lot of mass-appeal going for it. Of course, it is mass appeal that has brough America its McDonald’ses and other lowest-common-denominator monstrocities.
