This delusional but absolutely vise-gripping fear they have just will not enable their base to change. The plain truth is that the old, white, majority male base is riddled with ethnocentrism, racism, and FEAR. They are absolutely gripped with a fear and hate that is CONSTANTLY fed to them by right wing talk radio and FAKE News tv. Their old strategy used to be, "Divide the electorate by getting 51% to hate the 49%, and we win." The problem is, the 51% is now the 49-and-dwingling percent, and dwindling FAST. No, the radical right base of the Republican Party is DOUBLING DOWN on their fear and hate because they are so afraid that they will become the numerical and political minority.
The Republican leaders and politicians are driven by their Rush LimpMind-listening radical base. Not the other way around. America is changing, and instead of moderating the embracing the change, they are doing just the opposite. In addition, they are not moderating on their policies either. Most Americans want adequate government and a secure retirement, not a double down on FAILED trickle down. They are out of step with the majority on ALL fronts. They are numerically in the minority, philosophically in the minority, and in the minority on policy. Pretty bad place to be.
