The flaw in your assumption is that Obama doesn't receive any delegates in Michigan.  He picked up most of the uncommitted delegates at the district conventions

Popular vote totals are an inconsistent measure anyways.  It completely invalidates any caucus (MN becomes 1/4 of what MO is), and Obama wasn't even on the ballot in MI.

All this is about is finding some sort of measurement that Clinton can argue is a reason to overturn the will of the states.
