Restructure the Senate

Today in the NY Times, there is an article about a lawsuit seeking to expanding the house, so that the "one person, one vote" rule could apply between state lines, expanding the rule from its current interpretation which is intrastate (i.e. congressional districts within PA must represent the same number of people as other districts within the state, but don't necessarily have to represent the same number of people that districts in DE do). The lawsuit is seeking to expand the house from its current 435 members to anywhere between 932 and 1,761 members.

While I generally sympathize with this movement, an easier way to have more proportional representation would be to abolish the Senate. Or at least do things how Germany does:

• Every state is allocated at least three votes.
• States with more than 2 million inhabitants have 4 votes.
• States with more than 6 million inhabitants have 5 votes.
• States with more than 7 million inhabitants have 6 votes.

Obviously the population numbers would be different, but why focus efforts on restructuring the House when it is much more reflective of population than the Senate?

PS I think this is the font/size I will be using from now on. Like? Dislike?
