Clinton Adds More Delegates Despite Sanders Narrow Michigan Win

As the USA Today headline correctly stated, For the Record: Sanders wins headlines, Clinton wins delegates. Pre-vote polling in Michigan had Clinton winning by between 5 and 20 percentage points, so Sanders' win, even though it was by less than 2 percentage points, has to be considered an upset. However, Clinton's massive 66 point win in Mississippi means that overall on March 9 she picked up more delegates than Sanders.

The NY Times Upshot has a good explanation of how Sanders' Michigan win doesn't change the probability of a Clinton nomination.
