Everyone is free to compromise their ideals, their values, and their principles to justify voting for a bad guy. In fact, that is what most of the US voters do election after election, so I don't expect it will be any harder for them to do this time than it is any other election year.

The statement "A person may believe in communism, and yet still has to work for a living" shows a profound ignorance of facts. Communism doesn't have anything to do with working vs not working. It has to do with distribution of the wealth that is created by collective work, and an opposition to allowing individuals and nowadays individual corporations acting legally as entities with the same rights as individual persons, amassing wealth/capital which is inherited, stolen, extorted, etc. from others.
