Some liberal thinking people are suggesting that the constitution be changed in regards to the number of senators assigned to each state. According to existing law each state gets two senators. Since the country is now divided between red states and blue states the red states have an advantage since 30 of the fifty are red. This means that the senate will tend to remain in control of conservatives. In the last election red states had a population of 180 million and blue states at 140 million. The trend is that on average people are leaving blue states and moving to red states. This has less to do with politics and more to do with weather, economic activity and taxes. On average blue states have higher state income tax rates and they are continuing to move in that direction and meanwhile many red states are lowering their state income tax rates. Two years ago Minnesota raised their taxes and this year Iowa is lowering their taxes. One of the main reasons for these differences is that blue states tend to have better welfare benefits and of course this cost more and thus higher taxes.
