The answer isn't something we should accept as an opinion, though. For example, laws prohibit the federal government from (direct) involvement in elections.

I think you are confused. The constitution explicitly grants Congress the right to pass laws regulating federal elections:

  > The Times, Places and Manner of holding Elections for Senators and Representatives, shall be prescribed in each State by the Legislature thereof; but the Congress may at any time by Law make or alter such Regulations, except as to the Places of chusing Senators.
