Here's how we're applying labels to candidates and legislators based on the statements they've made, and the actions they've taken to protect or limit abortion rights.
We don't believe abortion rights should be a party issue, but unfortunately votes on these issues commonly fall along party lines. We've seen the majority of Republicans vote to limit abortion rights, and the majority (but not all!) Democrats vote to protect them.
In cases where a candidate has no voting record, and we haven't found a public statement on the subject, we can use party affiliation to take a best guess. Plus, we have to assume that if the candidate is silent on such a pressing issue, they're comfortable with us making such an assumption.
