Republican EV drivers outnumber Democratic EV drivers in many states, based on voter file data and vehicle records. In nine of the 31 states and DC that register voters by party, for example, more Republican voters are linked to records of electric vehicles – including insurance and repair records – than Democrats. Republicans, independents and third-party voters associated with electric vehicles also exceed Democrats in 24 of those states. There is a mix of market factors, such as consumer awareness, infrastructure, incentives and availability, that drive sales. States that have more of those things, such as California, have more consumer interest. And while the new state-level evidence in the adoption of electric vehicles might show less of a partisan divide, one left-leaning state still has the most in the country. More than one-third of electric and plug-in hybrid electric vehicles were registered in California, according to data from the US Department of Energy in 2022.
