There is an opinion piece in the NY Times, making the rounds, which seems to advocate changing the number of justices on the U.S. Supreme Court to get around the conservative rulings of the current Court.
It says in part:
"If the current five-man majority persists in thumbing its nose at popular values, the election of a Democratic president and Congress could provide a corrective. It requires only a majority vote in both houses to add a justice or two. Chief Justice John Roberts and his conservative colleagues might do well to bear in mind that the roll call of presidents who have used this option includes not just Roosevelt but also Adams, Jefferson, Jackson, Lincoln and Grant."
This post says yeah, but look what happened to them.
