What are 5 major weaknesses of the constitution

The United States Constitution provides the foundation for a strong central government with authority to regulate interstate disputes and commerce, enforce citizens' rights and defend from hostile forces. However, much of it is too vague to provide definitive interpretations. It can be amended, but the process is slow. Citizens vote for representatives directly but don't get a direct vote on policies. There is no way to address bipartisanship.

They made a checks and balance system to equal power within the branches. the "check" meant that one branch would watch one branch and "balance" them if they were too powerful. if you want more info on this, i would just google checks and balance system.
