Perhaps they see no hope for the Democrats. They may be right. Unless the Democrats learn to play to their strengths, Republican rule is inevitable. The Democrats can be very good at appealing to the voters' sense of fair play. This means not advocating special privileges for people because of their race, gender, or sexual orientation.

Republicans must be defined as being out of touch with the concerns of middle-class America. This is very easy. The Democrats must turn the family values issue against the Republicans.
