Improvements that might make our federal system work better: Eliminate the Electoral College. Put a three-term limit on senators, and have senators represent every 2 million members of the population (Wyoming would have one, and California would have 18). Abolish lifetime terms for the Supreme Court. Elect justices to two nine-year terms with staggered elections. Rewrite our Constitution by discounting items not pertinent and adding those that would be relevant today and into the future. Go to mail-out voting ballots that can be returned by either mail or plenty of secure ballot boxes. Bring back truth in politics. If an elected official lies during campaigning, he or she would be removed from office and then serve time in prison, just as one who commits perjury.
Plan the future by what we want to leave for our grandchildren, not by how much profit we can amass. Separate lobbyists and religion from politics.
This might make a good start.
