On today's What America's Thinking, a new Hill-HarrisX poll finds 52 percent of voter support increasing the number of seats on the U.S. Supreme Court. This survey was conducted online within the United States from October 25-28 among 2,824 registered voters by HarrisX. The sampling margin of error of this poll is plus or minus 1.85 percentage points. The results reflect a nationally representative sample of registered voters. Results were weighted for age within gender, region, race/ethnicity, income, political party, and education where necessary to align them with their actual proportions in the population.
