Sort of, yes, as John Sides reports:
Importantly, the public has not moved in a conservative direction in all issue areas. For example, support for same-sex marriage has been increasing across all states. It is also worth noting that our findings on the 1960s and 2000s hides important shifts in policy mood between these periods, such as increased policy liberalism during the 1980s. However, when it comes to support of government programs, the net conservative shift is clear. Considering the evidence that inequality is near an all-time high, this may seem like a surprising result. Prominent economic models, for example, expect that as the rich get richer, public support for government policies like spending more on education, infrastructure, and job creation would increase. Instead, across the country, the public’s policy mood has moved in a conservative direction.
There is more of interest here.
