On the contrary, most that vote have no idea what is going on. That would imply then that he who wins must have been the best available choice. Thats is of course if you are assuming that the electorate is rational, which I would posit they are not.
How many people vote based on an inherited like or disdain for whom they vote? Most I would wager. The vary fact that issues such as gay marriage, global warming, and evolution can sway and electorate proves that point that many have not shown themselves responsible enough to vote. Is that eletist? Perhaps.
As for the test, why does it have to be biased? Facts do exist, do they not? Is evolution the best available explanation? Is anthropogenic global warming the best available theory? Do price controls work to the benefit of a market economy? The only bias in these questions is that of truth, substance, and reality.
