Elections have been close like this for quite some time now. Doesn’t mean too much.
It means rather than worry about changing your approach completely, you need to:
1. work on turning out better
2. message better.
You do not need to abandon your philosophy as the Dim and the MSMediots always try to say when an Obama wins by a 300,000 vote “landslide” like this. Notice Reid is already moving to limit minority rights in the Senate in reaction to this landslide.
