The tea party is not a real political party. It is a political instrument opposed to the whole political system. Tea party proponents vow no compromise and virtually say no to everything. They demand no or little government and no regulations for banking, transportation, environmental concerns, etc.
Tea party proponents seek to privatize most everything, including education and medical care, and they seek to abolish Social Security and other safety nets set in place to protect the average American.
We need a strong two-party system, not a weak GOP without direction. The GOP needs to get its mojo back. I predict that the old GOP will be intimidated by the tea party, causing a split culminating in the tea party forming its own party. That will help the Democrats win the next election, which incidentally is fine with me.
