I'm just going to write something here which may get me into trouble but I truly believe it, it's a problem and I don't know what should be done about it:
A lot of voters on both sides are stupid. No I am not talking about uninformed (though most stupid people are uninformed as well), I'm talking about not very bright. There are stupid people voting for Hillary Clinton and Bernie Sanders: you know who they are because when they get interviewed they offer incredibly dumb reasons for doing so.
And Donald Trump has the largest number of stupid people voting for him that we've had in some time. Normally most stupid people don't worry me too much because they don't vote. But a populist, exciting candidate like Trump brings out the dummies as if they were attending NASCAR or a monster truck show. Everything Trump says attracts these people because he dumbs down all issues, offers slogans and quick fixes rather than real solutions, and is belligerent which is something stupid people enjoy.
Because we have a democratic system (and I'm not in favor of any other kind, don't get me wrong) the stupid people have as much right to vote as anybody else. But I don't see why we need to encourage them to do so. I would prefer an oligarchy of smart people running things around here.
You understate the problem.
It's not just stupid or uninformed people who are ill-equipped to be astute voters in today's elections. It's nearly everybody.
The problem is that the policy issues that dominate today's debates are
complicated. Take campaign finance reform as an example. You are neither stupid nor uninformed, but you can't carry on a conversation about any specific proposals for reform that might be appropriate. The specifics of health care reform are also really complicated. Trade policy. Labor relations. What's going on in Libya. NGDP targeting. Criminal sentencing guidelines. A new Glass-Steagall? Something about loopholes for hedge-fund managers? The effect of energy policy on climate change? Subprime mortgages and credit-default swaps? Farm subsidies...
Nobody can be an expert on all of those things -- very few people are experts on even one of them -- and yet they are complicated enough that competently evaluating specific policy-proposals on any of those topics does require some expertise. They are subjects that cannot be covered fruitfully in oral debates. Candidates could publish heavily footnoted (and ghostwritten) white papers on them, but few voters would have the capacity to read and understand them even if they wanted to, and pretty much nobody would want to.
The result is that political campaigns are not really about the issues, at least not in meaningful depth, and really cannot be, because we are pretty much
all too stupid or uninformed for that to work. Instead of debating the merits of individual provisions of the TPP, we tend to get vague statements about how free trade is good or unfair trade is bad.
We muddle on in the hope that the wisdom of even an uninformed crowd can get more things right than a despot or a dartboard. But the problems you identify would not disappear, or even perhaps be much diminished, if only we could mute the influence of stupid people. The problems run much deeper than that.
