What are the key features and ideas of the US constitution

The US constitution should be understood as a libertarian work. Written in the aftermath of the French revolution, (1700's)the constitution aimed to produce limited government through a separation of powers. Thus the constitution was codified (written down). We can analyse the 3 main elements of the constitution methodically Judiciary: Separate from the Legislative and Executive branch. Judges are given judicial independence and thus make 'landmark' decisions on previous/new law enacted by the exec/leg, thus providing a 'checking' role Exec: Framers hugely limited the powers of the executive, in periods of hyper partisanship, the phenomenon of the 'lame duck presidency' best represents this. Presidents usually get to nominate member of the Supreme court but perhaps their most significant power is the VETO, which can overrule congress. Legislative Branch: Separate to Exec unlike UK fused system. Can override the VETO of the president and also reject his nominations, thus is arguably the most important of all the branches of government. Key role of representation while ensuring limited government but preventing presidential legislation that infringes upon the key constitutional terms of freedom/liberty/justice.
