A method for the American people themselves to petition for, and have awarded, a public/popular recall vote for the President and his cabinet. We also need to alter the electoral college to better reflect popular vote and defeat gerrymandering.
It's more what I would take away: the electoral college system, which was created for an older time when campaigns couldn't be seen by most of the country--the "vote by state" system made it so that politicians wouldn't limit themselves to the most populated areas. But now politicians limit themselves to "swing states", so what's the difference? The fact that if you're in California your vote is worth less than someone in Ohio is unacceptable.
If the Justices' terms were not lifetime, their political views would be less entrenched over time. Also, their approval process would be less of a One-off novelty. As for Congress, I don't have to elaborate how beneficial new blood would be to that body.
Congress goes without saying. Oh man.... I think more moderate thinking might result from that by not letting extremist candidates to become too entrenched.
