The poll was conducted March 24-28, 2016. The full sample includes 1,405 registered voters interviewed by cell phone or landline, with a margin of error of +/- 3.3 percentage points. Results for the Republican primary are based on 471 likely voters who say they are certain they will vote in the Republican primary in April. That sample has a margin of error of +/-5.8 percentage points.

For the April 5 Wisconsin Supreme Court election there are 957 likely voters with a margin of error of +/- 4.1 percentage points.
