I mentioned only single-issue voters on abortion, not "most people."
You're not getting my point. That fact that most people feel that Roe is safe allows otherwise pro-abortion voters feel safe to use other issues to decide their vote.
Once these voters get the feeling that Roe is under serious attack and close to falling then these voters are going to suddenly become single-issue voters.
Most of the women I know don't think much about abortion but want the right to chose for themselves. Even so, they currently vote GOP because of the perception that it is the less socialistic party.
If they began to believe that Roe was about to fall then they would become single-issue voters and go for the dems.
