You cannot change it back to state appointing Sentators. It would be a potential disaster. With creativitiy and the right people placed in power it's possible to draw districts so that one party can dominate the elections. Say you have a state with 1M people where 60% vote party A and 40% vote party B. For simplicity, let's say there are only 5 districts. Each district has 200,000 people. It's easy to see that 3 state reps should be from A and 2 should be from B. However, party B gets the districts drawn in their favor and look what happens:
Code:
District A B Total
1 180,000.00 20,000.00 200,000.00
2 80,000.00 120,000.00 200,000.00
3 80,000.00 120,000.00 200,000.00
4 80,000.00 120,000.00 200,000.00
5 180,000.00 20,000.00 200,000.00
Total 600,000.00 400,000.00 1,000,000.00
Now instead of having 3 from A and 2 from B it is switched. Now the minority party gets to put their sentators in office and the whole system has been fucked.
One of the first things we should do is we should re-draw all congressional districts. Absolutely no voting data should be used during this process.
