The demographic issue is more than just race. It is clear the metros are democratic bastions that will vote 90+% for democrats whether they want to or not. The Dem machines in the metros will turn-out millions of votes one way or another (even dead people). The Repubs have to look at the Burbs and rural areas to overcome the Dems automatic adavantage. The problem is that all demographic charts show the metros growing and populations becoming more urban, not less. Urban pops want more government intervention for a myriad of services. Tha small government argument just does not go to far in such an enviroment. So it is a daunting task to overcome such an advantage, not impossible now, but daunting if the Dems get out their vote.
