Richard Thau, who conducts focus groups with swing voters, said his recent work finds that many young voters support the goals of the protests but are only lightly committed to the cause. “Support was a mile wide and maybe three inches deep,’’ said Thau, who conducted two focus groups this week with independent voters from across the University of Wisconsin system, all of whom were too young to vote in 2020. “It became clear that these students had empathy for what the people in Gaza are experiencing, but most would not go the extra mile to relieve the suffering of the Palestinians.’’
