It didn’t mention it in this article, but the NY Times reported that Bolick directly referenced her own pregnancies in debate, one of which was not viable:
Before casting her pivotal vote, Ms. Bolick stood up and began a long, deeply personal speech describing her own three challenging pregnancies, including one that ended with an abortion procedure in her first trimester because the fetus was not viable.
“Would Arizona’s pre-Roe law have allowed me to have this medical procedure even though my life wasn’t in danger?” she asked.
Like a true Conservative, she only came to her decision because it affected her personally. Still, it was enough to push it through.
