What are the major disadvantages of our written constitution?

1.  The complicated government it sets up, with power distributed between two houses of Congress and three branches, is prone to gridlock.  Our government is not designed for efficiency, but rather to best protect liberty.

2.  Because the Constitution is so hard to amend, we are stuck with anachronistic provisions that most people think are a bad idea.   (Some might argue, e.g., this is true of our use of electors to choose a president, the right to bear arms, or the right to a jury trial in federal cases involving more than $20.)
