Major structural reforms to American government, including any direct abolition of the Electoral College, cannot be accomplished by ordinary legislation and require broad national consensus.
Changing the rules written into the Constitution is intentionally difficult and requires overwhelming agreement from both Congress and the states.
The difficulty of amending the Constitution shields foundational rules from shifting political majorities but can also make widely supported reforms hard to enact.
An amendment can be proposed by a two-thirds vote of both the U.S. House and Senate, or by a constitutional convention called by two-thirds of state legislatures.
A proposed amendment becomes part of the Constitution only after being ratified by three-fourths of the states, currently 38 of 50, through either state legislatures or state conventions.
Some reforms pursue similar goals without an amendment, such as the National Popular Vote Interstate Compact, in which states agree to award their electors to the national popular vote winner.
