Voters vote for many reasons. Most identify with a few, perhaps 10-15 major reasons. Then narrow it down to a half dozen issues of most importance. For some its guns, government involvement in the economy, religion, the USSC, military spending, etc. Not everyone is a political animal so to speak like the participants in this forum. Most people tune out issues that they think don't effect their lives. That doesn't make them stupid, racists, fascists, etc.
Its why most republicans don't recognize the dangers associated with trump. The US survived one experience with the cancer of trump. It would survive another. But I wouldn't wish cancer on most anyone.
