In 2022, the proportion of households which are occupied by owners stood at 65.9 percent.

Renters are politically invisible in the United States due to the economic situation. Rent will continue to rise to unsustainable levels and nothing will done. As Charlie Munger (Berkshire Hathaway #2) says: "Show me the incentive and I'll show you the outcome."

Given how razor thin election margins are, ~33% of the population is far from a invisible class.

For a variety of reasons, homeowners vote. Outside New York City, which unsurprisingly has solid tenant protections, American renters do not.

Correct. Dated, but related and a classic: "We find that neither demographic nor attitudinal attributes explain [people who have recently moved's] lower turnout. Instead, the requirement that citizens must register anew after each change in residence constitutes the key stumbling block in the trip to the polls. Since nearly one-third of the nation moves every two years, moving has a large impact on national turnout rates."

The authors suggested "linking the maintenance of registration to an action that is usually an intrinsic part of moving" such as the "change-of-address notice at a local post office." Interestingly, "holding elections on Sunday, making election day a holiday, or extending the hours that the polls are open...are designed to facilitate people who are registered" and would thus "do little to improve turnout."

This is different from the proportion of adults in the US that own a home. Many non-homeowners live in an owner occupied residence.
