One 6 year term for President

Currently any 1st term President spends not more than 18 months actually working on the country. He has his honeymoon, 1st 100 days, then halfway through year two starts working for re-election.

Let's eliminate that need and give a President 6 years to do his/her job. They can work right up until they leave.

While we're at it, let's impose 3 six year term limits on the Congress and SCOTUS. At most they can serve 18 years and we can turnover 1/3 of each branch every 6 years!
