A YouGov/Economist poll in January asked respondents if they approved or disapproved of "the executive order that freed all slaves in the states that were in rebellion against the federal government." That executive order is better known as the Emancipation Proclamation.
Thirteen percent of respondents — and "nearly 20 percent of Trump supporters," the [New York] Times reports, compared with 5 percent of Marco Rubio's — said they disapproved of it. . . . An additional 17 percent of respondents said they weren't sure.Via Vox.
