What do you mean it would have to be on the ballot in Nov.? We don't vote on laws, that is what Congress is for.lots of political ads about abortion from, Harris, trump, and congressional candidates. what a strawman campaign; these officials have no say on this issue. the SCOTUS gave it back to the states; its either on the Nov ballot for the voters, or up to State legislatures. Not Feds.
If a federal law is passed by congress that mandates a federal minimum guideline to the states, that states they have to allow abortions at a minimum level,(in cases of rape, incest, or health threatening pregnancy, and/or before so many weeks pass) then for a short time that law is good. The supreme court may decide to rule on that law's constitutionality, but that is the Supreme Court's decision. It is not automatically decided, before they even try to pass a law on a minimum guidelines, that this law is unconstitutional.
You truly don't know how government works, but still make dictating statements on it all the time.
