That's a swell idea, but it is all but nonexistent in major news coverage in the US at the moment. I suppose this sort of thing waxes and wanes, but the general journalistic approach seems to have migrated from "present all the facts" to "inform all the viewers".
Despite my personal political leanings, I really think Fox is in large part to blame for this. They are a decidedly, unabashedly right-leaning news organization, created as a counterweight to the other big three organizations, all of whom tend to lean more left. I think Fox's assault on journalistic neutrality really opened the door for the media climate we have today.
Luckily, that is what the internet is for. Television news cannot hope to keep up. Watch the ten minutes of pundits, then get the stories from whatever organization covers them best.
