Political identity/label is distinct and separate from preferred policies, especially when those policies arent identified with a right/left label (not everyone is as familiar with the partisan origins of various policies as most DUers are)
For 40+ years, republicans worked diligently to transform to word liberal from a simple descriptive term into a pejorative epithet.
It worked, and the number of people willing to identify as liberal dropped sharply, but support for liberal policies did not.
Majorities of Americans, regardless of party registration or political identity, support the following progressive policies:
Reproductive rights
Medicare for all
Marriage equality
Sane gun laws and regulations
Tax hikes for billionaires
Collective bargaining rights
Minimum wage increase to $15-20/hr
Campaign finance reform
Regulations to ensure clean air and water
Laws to mitigate the effects of climate change
Restrictions on the conduct of ICE agents.
Now, the size of that majority support varies depending on how those issues are framed and phrased in the survey, but as long as they arent linked to a particular party, they get majority support. (IIRC, Pew research is a good source for this data, as is the Harvard survey - extremely large sample sizes with low MOE)
