I wouldn't expect that your digest would force you to investigate things that don't interest you. The whole point, in fact, is that it's your digest reflecting your interests. Because you and I share an interest in politics, from opposite perspectives, I'd find your digest interesting because it represents your conservative take on politics; your coverage overlaps my interests to a high degree.
You mention the failure of most news stories to link to supporting documents. That's one of your strengths, and another reason why your digest would be of particular interest. That's your added value.
