Someone once explained representative democracy this way: Choosing a candidate is like riding a bus. None of them are going to come directly to where you are and none of them are going to drop you off at your exact destination. The best you can do is choose the one that gets you as close as possible in the shortest amount of time. Sometimes you’re not even gonna get that close and you’ll still have a long walk to your destination, but at least you’ll be closer than where you started. Sometimes you have to take one bus then transfer to another to get to your final destination.

When the alternatives are buses that are traveling the opposite direction, your best available choice becomes very clear.

The place where this analogy falls apart is that by not taking either bus, you may actually lose ground and get further away from your destination. So I guess when the alternative is a bus that stands less than a 5% chance of arriving, you ultimately end up being shoved onto the bus that the majority of people are riding.
