Politics is about how people organise themselves so, yes, I suppose moral decisions come under that heading in a general sense.
As does, I suppose, deciding whether any particular decision is moral, immoral or amoral. But, as with all human affairs, there will be disagreement about which category any particular decision is placed in.
As this thread illustrates. Some people assume that all actions by a Tory government are, by definition, evil/immoral. Some people don't think it is evil and immorality that drives Tory politics. You don't have to be a Tory to take the latter stance. I know several people who, though delighted when Tony Blair first became PM, are far less keen on him now.
