The Electoral College is outlined in Article II, Section 1, of the U.S. Constitution. Nonetheless, Democrats have introduced a resolution to abolish the Electoral College. There is no doubt they want to end it, but a resolution carries no weight.
The College gives each state “in such manner as the legislature thereof may direct” electors equal to its representation in Congress.
Abolishing it would take a Constitutional amendment, which would require the votes of two-thirds of the U.S. House of Representatives, two-thirds of the Senate, and three-fourths of the states.
