I have a really cheap bridge to sell you, it's powered by a perputual motion device. You can raise the money to buy it by helping me extract the fortune of my Uncle, a former military commander in Nigeria, just reply with the details of your bank account.

If you reply within seven days you get exclusive access to my fat burning natural rose petal extract pills!

Don't listen to those people who claim it isn't this easy to be rich and thin, they're just haters. I'm the only one looking out for you!

You're completely missing the point. The 'cost' of voting is the same no matter who you vote for and even if you chose not to vote someone will become president. So for many people they see the choice as being between someone who might fuck them over and someone who will fuck them over. I'm not a Trump supporter, but it's not that hard to see his appeal.

The 'cost' of voting isn't about paying money to vote. It's about the laws and policies that are brought in by the people in power. Taxes are a very obvious direct one, but just diverting tax money from "good stuff" to "bad stuff" is a fairly direct cost too.

Someone promising you unreasonable things is much more likely to be fucking you over. Some would say that promising you unreasonable things and then fucking you over is the basic thread of all politics, Trump is just taking it several steps further because apparently people have become unmoored from the reality of government and so cannot judge what is unrealistic anymore.
