Casey Has Significantly Lead in Pennsylvania

ActiVote’s August 23, 2024 Pennsylvania U.S. Senate poll shows that the 3-term incumbent Democratic Senator Bob Casey leads his Republican challenger David McCormick by 9.8%. 

The poll was among 400 likely voters, has an average expected error of 4.9%, and was in the field between August 3, 2024 and August 23, 2024 with a median field date of August 13. 

Casey leads among most groups, except for rural voters, the elderly, Republicans and, surprisingly, those with the highest education. Among ethnic groups, Casey and McCormick are tied among White voters, who represent 80% of the electorate in Pennsylvania. As each of the other ethnicities had an unweighted sample of less than 5%, we do not report separately on their leanings.
