I do not see a connection here. Abortion is distraction not because it pertains to women's rights, but because it is revisiting of an old battle (won in the Roe v. Wade decision), in the time when the economic spoils are being divided by the corporate elites. As far as I can tell, the prolifers do not voice an anti-womens' rights agenda, on the contrary, they often portary themselves as protectors of those rights against the medical business that benefits from abortion. I can see that such rhetoric can easily resonate with working class, for whom "choice" is but upper class abstraction. These folks have little choice in their lives to begin with, as they are usually bossed around by those who talk about "choice."
I think the ability of the Right to capture the attention of these folks and place it under the rubric 'pro-life" is a perfect diversion - otherwise these people might be demanding comprehensive economic reforms that would make life of multi-child families (usually working poor) easier.
