I've been mulling whether I like this and changing elections to every 3 years:
-president - 3-year term, eligible to serve 3 terms (so nine years)
-House - up every 3 years
-Senate - still a 6-year term, but you alternate who is up for election between the 2 seats each time
I'm strongly in favor of this idea (including the 3-term eligibility for the president). I really think we'd benefit a lot from holding elections every 3 years instead of every 2. Way too much time is spent on electioneering instead of governing.
