Newly formed politically mismatched couples in states with abortion bans were 11% less likely to remain together in 2022, relative to mismatched couples in states with abortion protections.
There are no clear differences for matched couples, nor differences before or after the bans.
Political differences matter for relationship duration.
In a new study, @rfunkfordham.bsky.social and I identify 60 million couples in the US and find that, even after considering variables like income, those formed by partners registered to different parties are ~14% less likely to stay together
