Many lower income whites do not vote. This is rarely because of indifference and ignorance. It is because of the knowledge that many Republican politicians would like to scale back domestic spending programs that benefit them, such a Social Security, Medicare, and unemployment compensation. Republican politicians are also opposed to raising the minimum wage and strengthening labor unions.
Lower income whites also know that many Democratic politicians lack their concerns about crime and immigration.
Yes Republicans have done a good job to convince these people both parties suck. And as long as they don't vote, Republicans are good with that. Just don't vote Democratic.
Us Democrats encourage them to vote because we assume if they're going to, it'll be for us. But I wasn't so sure the last 2 elections. I think a lot of poor whites voted for Trump because he was different and would fuck with the system. It was a great message. But then Trump used it anytime he didn't get his way or when he got caught breaking the law. Witch Hunt. Even when Republicans went after him, they were just deep state globalists.
