But that liberal tendency does not translate into how customers view one of the more controversial topics faced by state and local governments today: whether or not to regulate these new companies in the same manner as traditional taxi and hotel companies, which must follow strict rules on car insurance, provide access to customers with disabilities, and pay local hotel taxes.
It remains unclear what the political implications of these dynamics will be as city councils and state legislatures across the country attempt to get a grip on Uber and Airbnb.
The companies have used their billion-dollar war chests to effectively mobilize users against regulations in some cities.
Last November, voters in famously liberal San Francisco rejected a ballot initiative that aimed to strictly regulate short-term rentals, after Airbnb pumped more than $8m into the campaign to defeat it.
But voters in Austin, Texas rejected a nearly $9m campaign by Uber and Lyft to repeal regulations on ride-sharing in the city earlier this month.
The study also found an interesting racial disparity in users of home-share services that does not exist among ride-hail users – 13% of white Americans have used home-share services, compared to just 5% of blacks and 9% of Latinos.
