>Who is going to pay the salary of all these senators?

The people who pay them now. They get paid 200K a year, so if, in 2004 we decided that they should get paid 150K a year (which I think is still 3 times the national average *1) and that there should be four senators from each state, we would be going from a $20 million Senate salary to a $30 million salary. Considering the war on Iraq will cost us about $200 billion, a measly $10 million should be swingable.

Would that work for a start?
