It would be interesting to see these rates and their political affiliation. My guess is that it would be pretty mixed. Seems the “libs sterilizing themselves” is a clear conservative cope.

That said, you can probably query the CDC Wonder dataset to see the breakdown of vasectomies by state.
I actually think overturning Roe will accelerate abortions in some regions (and completely stop others). There were previously limits on abortions based on age. In Colorado, you can now abort up to birth, for instance.
Imo this will lead to a much larger change in the fertility rates.
