Following the Supreme Court’s decision to overturn Roe v. Wade, advocates and politicians are calling on states and congress to codify Roe. But what does this actually mean for abortion rights? But here’s the twist: Despite some politicians saying they want to “codify Roe,” Congress isn’t looking to enshrine Roe in law. Before the Supreme Court ruled in Loving v. Virginia that banning interracial marriages was unconstitutional, a number of states still banned such unions. Liberal states like Massachusetts have passed laws that codify Roe v. Wade.
