Very difficult to say, abortion is many voters is not a major issue if you think about it.
It wasn't an issue for many voters because they saw it as settled. Even many people who personally are opposed to abortion were okay with the choice being left to the woman.
The idea that the Republicans are "coming for your uterus" has the potential to be as powerful a calling cry as the Republican's "their coming for your guns".
I thought that the argument was that the original basis for Rode vs Wade was later applied to other rulings that granted various freedoms that some states wished to restrict. If one can be overturned, it may be a matter of time before the others are as well.
Precisely! The argument that supported Roe v Wade directly supported access to contraception, made sodomy laws unconstitutional and underpins same-sex marriage. And if you don't believe that these are under threat, consider that the self-same justice Thomas wrote, in his judgement that
Griswold vs. Connecticut (in which the Supreme Court said married couples have the right to obtain contraceptives),
Lawrence v. Texas (which established the right to engage in private sexual acts) and
Obergefell v. Hodges (which said there is a right to same-sex marriage) were "demonstrably erroneous decisions.”
And it is undeniable that bans on abortion will disproportionately affect poor people - who are more likely to be non-white - as they are least likely to be able to afford contraceptives. Not to mention that it is also highly unlikely that they can travel out of state for an abortion. And it's no coincidence that Federally-financed family planning services - which many in minority communities depend on - were severely cut back by the Trump administration.
On top of that, many the Christian fundamentalists who are behind this push genuinely believe in a literal interpretation of the Bible - seven day creation, six thousand year-old Earth, Noah's flood 3400 years ago, etc. They are emboldened by this and other recent decisions to the point that I've seen more than one of their most popular leaders make calls for homosexuals to be executed.
