Based on some modern voter theory McGovern will do just fine doing what he wants. ...
I got around to reading your first link at last. I found it frankly depressing. I'd be interested to know whether something broadly similar applies to nations that have proportional representation like say the Scandinavian countries.
I really like to believe that if we enact a good proportional representation system, that voters will wake up and start to pay attention to politics--that more of them will adopt it as a "hobby" in the article's metaphor--because OTL with our FPTP system and essentially two party system (the first does not automatically cause the second--the British Parliament pretty much always has a modest sized third party or two, and pretty often a cluster of very small parties, some ephemeral and some perennial though the relative size of their delegations tends to be grossly out of proportion to their overall support) people feel little option to influence the outcome in a gratifying way--as a hobby for those of us who have dived into it for any level, it is a bit like gambling--I like to think "I am struggling for the right side!" but then I don't want to suffer the down side of losing, so the rush is not enough for me personally.
Also I have a darker view of the alienation of most voters. To the author of that paper, it seems to be no big deal that most people just plain do not care, but I do believe, or anyway like to believe, that there is some nasty oppression going on here, that people are afraid to get into the game because if causes they can really care about come close to winning they can be seriously punished. Knowing this, knowing that "the house always wins" in the gambling casino metaphor, people sensibly stay away lest they get rooked. They form other interests and rigidly wall off politics as something they do not want to think about because it depresses more than excites them.
I like to think that if you change the game by enabling parties that have small but steady support to gain proportionally to the attention of voters they do command, then people would get more engaged and show up to champion those they see as fighting in their cause, and thus a more valid sample of the actual interests of voters forms and over time they learn what has traction and what does not and gradually get more and more accustomed to thinking seriously about policy and weigh in more consistently. Through positive feedback I hope the people get seriously engaged and mass democracy becomes a more meaningful thing.
But I do have a fearful suspicion that if I go to a nation where people do have a serious PR system, as apparently say the Netherlands does, I will find on the whole the same sort of indifference and whimsical relationship of the majority to party power blocks. That of course would raise the question of how come nations like Sweden could have the same party in power for 40 years straight, if its supporters were not seriously thinking about their options and resolving that the old party had served them well and was still on track to do so indefinitely. Rather than just pulling the lever for the same old party because it was habit or just what people from their part of down generally did.
