Think of it from an economic standpoint. People who vote for these Dems think they are going to loot the richest nation in history (the US). They are going to have their education loans paid off or their college paid for. They are going to get free healthcare. They are going to get treats and money. The Dems will make it all seem fair by demonizing the opposition. The Dem propaganda engine, which is the most powerful and damaging force this free nation has ever suffered, distributes the message.
Of course, there are some folks who vote for Dems for no other reason than they and their family or neighbors have always voted for Dems. But, in the beginning, they and the others joined the Dems for the loot, too.
None of them connect the reality of a Cuba or Venezuela with their voting but that is where they are taking us.
