The President:

1. Elected by We the People via the electoral college.
2. Limited to 2 four year terms with a maximum of 10 years served.
3. May be removed from office before his term expires, via impeachment and removal vote in the Senate.
4. A veto may be overridden by 2/3 Congress.
5. Must seek re-election after a 4 year term by We the People via the electoral college.

Congress:

1. Elected by We the People.
2. No limitations on time served (unfortunately!)
3. Must seek re-elected every 2 or 6 years by We the People
4. Legislation passed may be either vetoed by the President or deemed Unconstitutional by SCOTUS.

SCOTUS:

1. Appointed, never elected by We the People.
2. Lifetime appointments, never held responsible for their actions good or bad.
3. Decisions cannot be vetoed or overruled by any other branch of government or We the People. Only by a future SCOTUS, or Constitutional Amendment!

Basically SCOTUS is a 9-man Dictator-for-Life Branch of Government, that simply can dictate the law, with no repercussions, CHANGE MY MIND!
