Investigations at "The Drum"

COMMENT: ABC promotes "The Drum" as "analysis and views on issues of the day" however with its "investigation" into expenses of Opposition Leader Tony Abbott titled  How the taxpayer helped Tony Abbott flog Battlelines it appears to have crossed over into the realm of actual "News". Is this an opinion piece or a news story? In publishing this at The Drum (opinion) is ABC attempted to subvert its own editorial policy that provides stricter rules on facts for "News" items than for "opinion" pieces? Is this part of an internal power struggle within Auntie? Has ABC News missed so many of the big stories that ABC's agony Aunt "The Drum" now see fit to fill the gap? Is The Drum now so embarrassed by the performance of ABC News service that it now provides its own? Will The Drum now insist on going 24/7 with its ground breaking opinion pieces? 
So many questions, so few answers.
