What is wrong with this picture?

The two party system is the political paradigm that represents the emerging multi-national corporate state. Its function is to represent corporate interest, not the interests of stakeholders or citizens. As a result there remains a significant body of citizens and residents in the US who are not represented in the decision-making process. The term "marginalization" has long been used to describe people with no voice in the political process. Democracy is determined by the dollar amount that one can contribute to the campaigns of candidates.

This transformation of the two major political parties into contributor-based organizations has resulted in a shift away from traditional constituency groups.
Instead, campaigns consist of fund-raising contests in which millions of dollars are put on the table in the pursuit of favorable governmental allocations and regulations for the economic interests of a privileged oligarchy.

As constituency groups (defined simply as voter blocs) disappear in significance, here is an increasing convergence of interest of the two political parties seeking financial support from the same sources. In this context, the platforms and political policies of the two parties are increasingly homogenized. Trade policies, monetary policies, entitlements, the social safety net, foreign policy, and environmental policies become less based on whom the parties are representing, than who is signing the checkbook.
