"The issue of abortion has increased markedly in importance among Democrats following the Supreme Court's decision ending the federal guarantee of a right to legal abortion in the United States," Pew said in a statement accompanying the poll. "A majority of registered voters (56%) say the issue of abortion will be very important in their midterm vote, up from 43% in March."
However, the issue looks more likely to boost voter turnout among registered Democrats rather than win over Independent and Republican-registered voters, the release added.
Over 70% of Democratic registered voters rate abortion as very important while fewer than half (46%) said this in March, according to the poll. Meanwhile, views among Republicans have shown almost no change since then (41% now, 40% then), according to the release.
