This is a tough question, and one that you won't get a great response to, as it isn't a simple answer.
The biggest thing that scares me is we are losing our historical skepticism of government. Both sides want to increase the role of government in our lives; one in the name of foreign policy, one in the name of the domestic policy.
On the other hand, we are also losing our sense of balance. There definitely are things that we, as citizens, rely on our government for. We need them to provide infrastructure for the country, and ensure that the free markets are fair markets.
In more concrete terms, this has been reflected by the expanding powers of the office holders, the reduction of freedom and liberty in society, the national debt, and the insane Wilsonian notion of forcing democracy onto other countries.
