The chart above reflects the results of the latest Economist / YouGov Poll -- done between March 19th and 22nd of a national sample of 1,500 adults (including 1,267 registered voters). The margin of error for adults is 2.9 points, and for registered voters is 3.1 points.
Note that the chart shows that only a minority want voting to be made harder to do in this country. The majority either want it made easier or leave it as it currently is. The Republicans are not making any new friends with their efforts to suppress the vote (make it harder to vote).
