Speaking of "average", every political debate moderator should ask the candidates where they shop and how much milk and eggs cost. Ask them how much it is to fill up their car's gas tank. I don't necessarily think sortition is the answer, but I have more faith that the so called "hopelessly biased and ignorant average person" would address issues that affect me than I do with hopelessly biased and ignorant people like Trump, Johnson, Thune, Schumer and Jefferies, because I know they're only looking out for themselves.
