I simply cannot imagine anyone voting for either the Democrats or the Republicans anymore. It's unthinkable.

But there's effectively no one else to vote for in the USA (in any realistic sense).

That's what's so sad about it. It's a closed shop. It's a "choice" that is really no choice at all. It's an oligarchy, not a democracy. Real democracy ended a long time ago. The $ySStem now just goes through the motions of elections in order to fool people into imagining they still have a voice. Abraham Lincoln was already predicting this demise of real democracy way back in the 1860's. He said that big commercial interests would destroy it. He was right.
