If you want those people to change how they vote you need to stop talking down to them. "Hey stupid! You're voting for people that hurt you."

Or then again, maybe they just have a different opinion than you on what is important to them?

Surely nobody can be tricked onto supporting positions contrary to his interests. That would be impossible, since people are rational, educated and perfectly informed.

There is a minority of people who are actually completely out of touch with reality, so-called demagogues and populists, and to a less extent all politians: they are completely deluded in thinking that by repeating a point a thousand times they can mislead those perfectly informed masses.

If someone continuously keeps getting tricked into voting against their own self-interests, with the belief that their vote will actually benefit them, then yes, they absolutely deserve contempt.

As the saying goes: "Fool me once, shame on you. Fool me twice, shame on me." A large part of the American populace has been getting fooled repeatedly for decades.

It has not been established that they are voting against their own self-interests. You are just assuming you know what their interests are better than they do.
