Political parties tend to adhere to some particular theory of how government should be. Defined: "A system of ideas and ideals, especially one that forms the basis of economic or political theory and policy."
The effect of an ideology is to get everyone in a political party voting in lock-step, so that the party ideal is always supported, issues aren't considered outside of the ideological constraints or merits, the desires of the electorate are irrelevant, new ideas are unwelcome, and the world can march along toward disaster.
Guidance is the collective wisdom of the electorate, including voters and politicians. New types of solutions may be found, especially drawn from experience. Guidance is not paralyzed by ideology. It is practical. Guidance is open to opinion, not closed.
There is nothing about guidance that says people can't have ideals.
Guidance is not the willy-nilly voice of a bunch of people who have no opinion. It's a collective voice of strong opinion.
