Yes, exactly.
Romney went into election day thinking he was going to win. For Obama it was more of a nailbiter.
Many, many pollsters and pundits, on both sides, believed Romney was going to win.
The reason Obama won was because he used datamining techniques (see the PJ Media article on Catalist) to prevent his numbers from sinking past the point where Romney’s gain in voters would surpass them. That and Romney’s GOTV system (Orca - there’s a good Breitbart article on that) failed on election day.
Or was it sabotaged?
