6. The US Constitution is considered a living document for 2 main reasons:
It can be amended (changed). There have been 27 ratified amendments by now.
Its basic principles can be applied and interpreted differently at different times.
To successfully amend the constitution requires:
A proposal by a 2/3 vote of each house of Congress (26 amendments).
A national convention called for at the request of the legislatures of 2/3 of the states (1 amendment).

7. The first 10 amendements are known as the Bill of Rights, which places limits on the federal government power to reduce individual freedoms. It was adopted in 1781.

8. Some of the amendments are:
1. Addresses the rights of freedom of religion (prohibiting Congress from establishing a religion and protecting the right to free exercise of religion), freedom of speech, freedom of the press, freedom of assembly and freedom of petition.
2. The right to keep and bear arms, 1791
3. No quartering of soldiers in private houses during time of peace or war, 1781

9. The principle of limited government is basic to the constitution
The principle of limited government is basic to the constitution. It means absence of opportunities of power concentration by few people. It is realized through 3 features:
The federal organization of government (division of powers between the central government and the states).
The separation of powers among different branches of government.
The system of checks and balances.

10. Several academics have criticized the Constitution for specific shortcomings. University of Virginia professor Larry Sabato wants an amendment to organize primaries to prevent a "frontloaded calendar" long before the election to prevent a "race by states to the front of the primary pack" which subverts the national interest, in his view.
