Earlier quoted context omitted.
I think the takeaway is that government represents too many people and you cant satisfy everyone, so leaders listen to citizen action groups and lobbyists who are able to aggregate all these different viewpoints into more broadly popular legislation and show with their supporters that these ideas would be popular among a given electorate.
After having interacted with politicians, I am firm in my belief that most of them don't care about their constituents.
If politicians represented fewer constituents I think they'd be forced to care more about their constituents, if only because each individual voter wields more power. I certainly think that I have more power to influence my local politicians than I do my state representatives (let alone my federal representatives). My local politicians also live more proximate to me, and share more in the physical problems of the region. My US Senators live in my state, and that's about all they have in common with me.
