The Constitution fixed the problems of the Articles of
Confederation by the following. Article I of the Constitution, Congress
can regulate interstate commerce. It is also responsible for coinage and
only Congress can regulate tariffs; in the early days of the national government,
it was largely funded through land sales, excise taxes, and tariffs.
Article II gave the national government a chief executive whose job it
was to execute the laws. He had veto power over Congress, but Congress
could override his veto or even vote to impeach him in extreme cases.
