TIPP conducted an online survey for the League of American Workers from March 4 to March 6. The nationwide study had a sample of 1,720 registered voters. TIPP's network of panel partners provided the study sample. Upon the study's completion, TIPP weighted the dataset by gender, age, race, education, geographical region, and party to known benchmarks such as the U.S. Census and voter data. The survey’s credibility interval (CI) is +/- 2.5 percentage points, meaning the study is accurate to within ± 2.4 percentage points, 19 times out of 20, had all registered voters been surveyed. Due to smaller sample sizes, subgroups based on gender, age, ethnicity, and region have higher credibility intervals.
