No, he is not saying that you should not vote, but he is saying your vote is wasted if the person you vote for has no viable chance of winning.
To show how his logic works out in real life:
- Do you live somewhere where only a Republican or Democrat can win? Well, you must vote Republican or Democrat!
- Do you live somewhere where only a Republican can win? Well, you must vote Republican!
- Do you live somewhere where only a Democrat can win? Well, you must vote Democrat!
- Do you live in Communist Poland where only the atheistic, anti-Catholic Communist Party can win? Well, you must vote Communist!
Got it? Voting any other way is wasted. Do the right thing. Don’t vote on conscience or opinion or conviction or whatever. No one cares, and it is just a waste of a vote. Who have the masses chosen as viable candidates? Choose one of those candidates!
Okay, I am being mildly facetious, but really…people can vote for whomever, regardless of viable or not. There are different ways to approach the election process. Some are pragmatic. Some want to send a message. Both can make a case for their approach.
