As a result, the voice of the states influenced nearly all federal government policies:
Budget: Federal spending was established including the states' voice in the Senate (pre-17th Amendment), and payment from states for spending was approved through indirect taxation (pre-16th Amendment).
Taxation: Tax law was established through the states' voice in the Senate (pre-17th Amendment), and income tax was paid indirectly through states based on population (pre-16th Amendment).
Elections: Prescribed by state legislatures, except where Congress might regulate (Article I, Section 4), with states also having a voice through the U.S. Senate (pre-17th Amendment). States determined the election of electors for President (Article II, Section 1). Votes were first counted locally before being sent to central counting at state and federal levels to maintain local control. Congress was prohibited from interfering with how state legislatures prescribed Senators could be elected (Article I, Section 4), a provision violated when Congress proposed the 17th Amendment.
Appointments: New federal executive positions required approval/confirmation by the U.S. Senate (Article II, Section 2, Paragraph 2), the states' voice prior to the 17th Amendment. Similarly, federal judges require Senate confirmation.
Treaties: The President may negotiate and sign treaties, but validation needs Senate ratification (Article II, Section 2, Paragraph 2).
Local Legislation: Federal powers are enumerated powers by the Constitution, so local issues belong to local governments, except in cases directly impacting the union.
