First, a recent PRRI survey found that nearly half (47 percent) of Democrats said abortion is a critically important issue to them personally; 40 percent of Republicans said the same. That represents a dramatic swing since 2015, when 36 percent of Democrats and 43 percent of Republicans said abortion was a critical concern. Democrats are almost twice as likely today to rate the issue as critical as they were in 2011.

Democrats are also increasingly likely to say abortion is an important voting issue. A recent Pew poll showed that abortion is a far more central voting concern for Democrats today than it has been at any point in the last decade — 61 percent of Democratic voters said abortion is very important to their vote this year. In 2008, only 38 percent of Democratic voters said the same. That’s roughly the same percentage of Democratic voters who say terrorism, taxes, immigration, the federal budget deficit or trade policy is an important voting issue.
