Actually, this election is about something; what is probably the default subtext for all of them: The ability of these clowns to push how relevant they are to creating meaningful policy ever lower.
The real question is why anybody would expect anything else. This is, after all, government as "Reality TV" and, as such, it is the producers, with the hacks they employ to write the scripts, who have the last word in where the course of policy will get plotted. Where the producers, in this context, are the captains of capital who are not only ever more certain in their conceit of the value they create, but of their inherent right to be in charge of the show in the first place.
And lest you have any doubt about this fact just remember that "Dark Money" is soon to surpass ordinary influence spending. That this will also soon go over the billion dollar mark for every cycle is almost as depressing as how even that realization is becoming old news.
The bottom line here is that the fault lies with us. If we cannot find a way to take action and stop doing business as usual; stop playing the money game, this farce will continue. Just because its the only game in town doesn't mean we can't figure out a better one, and then make it happen.
