An ideology is any set of principles or biases or beliefs raised to the status of axioms or truths. Here it is proposed that the difference between a political ideology and a political philosophy is mainly a difference in status - a philosophy is a "grown up", fleshed out, published (by one or more people), comprehensive document covering many unrelated issues. An ideology need not be so universal or well established.

An ideology does not necessarily become a dogma or a faith, but it may, if the axioms are unmodified or "truths" unchallengeable.

Almost every political party avows an ideology of loose or strict form.

Capitalism and communism are leading ideologies that have changed definition over centuries, but generally correspond to extreme positions of right and left respectively, and each is often claimed to be an ideology, though their adherents claim they are common sense instead. Buddhism and Taoism claim likewise.
The Green Parties for instance avow the Four Pillars and extensive or operational extensions or implications of these.

Any ethical tradition is based on ideology of some sort:

Confucianism is an interesting exception. It is less an ideology than a commitment to a specific power structure and ethics, one seemingly specific to China. Zionism and other forms of political Judaism are also a situated ethics that doesn't work well in other places.
