Section 1: The right to an equal vote may not be denied to any resident 13 years of age or older for any reason.
Section 2: The Electoral College is hereby abolished, and the President shall be elected by a national popular vote.
Section 3: The United States Senate is hereby abolished.
Section 4: Wherever Redistricting is done, whether it be the United States House, State Legislatures, or otherwise, the power to draw the lines must be given to an Independent Citizens Commission.
And whatever other sections might be needed.
Why do you want to abolish the Senate?
It doesn’t seem to me to serve any real function the House doesn’t, except maybe helping to preserve state powers; it seems like the sort of thing that should be elected differently like the Sénat in France or appointed like the Lords here.
I'm sorry, out of all the things from our constitutional framework you could offer to the US, that is one of the worst. I would have a Senate over the HoL any day for here.
Anyway, mine would be around democratic and human rights, and also to reform the constitutional amendment process. If I was allowed another I would use it to strengthen public transport somehow, because it's my pet issue 😛
