Not even a joke so much as a literal interpretation of the proposed law. It only bans unsafe and unregulated abortions, and only up to the point of live birth. If it became a law with that language, how is that going to be interpreted by the courts? This attempt to inject partisan language cuts any actual meaning from the law. He’s trying so hard to manipulate the vote that the resultant law doesn’t even do what he wants it to. Irony is the humor here.
