> They don't need 60 votes to ban it. They just need the presidency, vice-presidency, 50 votes, and a Senate rule change to abolish the filibuster.
There aren't fifty votes in the Senate to get rid of the filibuster, and probably won't ever be. Enough senators respect the ideal of bipartisan consensus and deliberation to change the Senate into a version of the House.
> Why not? Getting an abortion is an act of interstate commerce, or else an act in which commerce within a state affects interstate commerce. The courts have granted the government fairly broad leniency in that area before.
It is hard to say. Laws against abortion hold someone criminally liable for abortions that violate state imposed restrictions - to date more a matter of state criminal law than interstate commerce. Congress is not usually in the habit of taking over entire areas of state law and telling states they can no longer legislate in that area at all, and criminal law has generally been understood to be an area where states have primary responsibility and Congress has secondary responsibility.
As far as affecting interstate commerce is concerned, Wickard v. Filburn is considered by conservatives to be among the worst (and least justified) Supreme Court decisions of all time. I wouldn't rely on the Supreme Court to expand or rely on it to cover a major new instance of Congress using it to supersede state law without state consent.
