The 17th Amendment

The Senate of the united states shall be composed of two senators from each state, elected by the people thereof, for six years; and each senator shall have one vote. The electors in each state shall have the qualifications requisite for electors of the most numerous branch of the state legislatures. When vacancies happen in the representation of any state in the senate, the executive authority of such state shall issue writs of election to fill such vacancies

This amendment sets that there will be 2 senators per state and if there are vacancies the people will vote for a new senator.

I think it's funny that a lot of people want to repeal this amendment just because its not what the original founders had in mind.

Once again, i think it's just really funny that people are so serious about this amendment when there are much more controversial ones.
