While I understand the implications, the headline is still pretty misleading. The article mentions no threat of rape. Of course, “your body, my choice” could be taken that way, but I read it as them lording their control over women’s bodies, not as a direct that of rape. Overall though, this is still bad. Like third act of a film with no happy ending in sight bad.
It looks like this 3.2M is the difference of the popular vote Trump received over Harris. A rough search looks like about 56.5% voter turnout amongst voting age population.
