From the summary:
Data for Progress surveyed key components of Bernie Sanders’s “Workplace Democracy Plan” and Elizabeth Warren’s “Empowering American Workers and Raising Wages” and found that the platform’s policies are broadly supported by voters. The policies tend to have broad support from Democrats, but many also have net positive support among independents and Republicans. In addition, we find that there is a potential key bloc of voters that either did not vote in 2016 or voted for Trump that support components of the platform, making them potential targets for 2020 election efforts. One caveat is important: many of these policies also showed high rates of voters having no strong opinion, meaning the numbers could change.
– A federal “Just Cause” law, which would radically change employee-employer relations and is included in Sanders’s plan, is somewhat or strongly supported by 56 percent of voters and opposed by 30 percent of voters. Even among Republicans, “Just Cause” is two percent underwater (42 percent support, 44 percent oppose).
– Expanding federally protected union rights to farm and domestic workers has bipartisan support and is included in both plans. Democrats support it at 66 percent to 21 percent, and Republicans support it at 41 percent to 38 percent.
– A ban on forced arbitration, which is included in Warren’s plan, is supported by 45 percent of voters and opposed by only 27 percent.
