So my first post says, one should never deliberately narrow one's scope of interests in politics. The second post says, deliberately narrowing one's scope of interest can be politically helpful. Huh?
Individual people, in making their voting decisions, should be as broad-minded as possible, consider as many different angles and issues as possible, and are irresponsible for doing otherwise.
Political organizations, in struggling to make progress toward their goals, must narrow their scope to focus on an achievable set of goals. To do anything else isn't irresponsible, necessarily, but it sure is ineffective.
TRIVIA FACT: What I just engaged in -- i.e. elaboration of nuance -- is referred to in the media as "flip-flopping."
