Romney got zero votes?

I don't know about you but this is just unbelievable...

"It's one thing for a Democratic presidential candidate to dominate a Democratic city like Philadelphia, but check out this head-spinning figure: In 59 voting divisions in the city, Mitt Romney received not one vote. Zero. Zilch."

Every polling station, there are Democrats and Republicans workers so no way Romney got a zero vote from all 59 voting divisions.

Obama is my president, I respect the outcome but results like this needs to be investigated in order to have a fair elections in the future.
