The title says almost everything I wish to say: There should be term limits for all! I do mean all, including the Supreme Court. Yes, I realize that would require an amendment to the constitution, but I’m okay with that.
Also, I strongly believe that there should be no poll results for elections until all polling places are closed (and that includes Hawaii and Alaska). You should not be leaving your place of employment after a long day of work only to find out that the president has all but been decided (based on conjecture, exit polls, etc.), making your vote somewhat futile.
While speaking about government, let’s throw in the idea that laws should not automatically last forever. They should always have an expiration date (10, 20 years?). At that time, they can be voted in anew, or left at the roadside.
Just my opinion. Yours may vary.
